1. Add more checks to bail out of 'needed' is greater than 'v_left'.
2. Simplify fallback logic
3. Do not set pf->num_avail_sw_msix in ice_ena_msix_range as it

This patch fixes a critical reset issue that resulting to the server
reboot when an Admin changes VF configuration on the host, for example
changing VF to Trusted/non_Trusted mode, the PF driver send reset
notification to AVF driver while also continue with reset flow. However,
AVF driver schedule another reset due to notification, which causes two
concurrent reset going on, and trigger lock up in the FW, with AQ call to
delete VSI.

The total number of queues available on the device is divided between
multiple physical functions (PF) in the firmware and provided to the
driver when it gets function capabilities from the firmware. Thus
each PF knows how many Tx/Rx queues it has. These queues are then
doled out to different VSIs (for LAN traffic, SR-IOV VF traffic, etc.)
To track usage of these queues at the PF level, the driver uses two
bitmaps avail_txqs and avail_rxqs. At the VSI level (i.e. struct ice_vsi
instances) the driver uses two arrays txq_map and rxq_map, to track
ownership of VSIs' queues in avail_txqs and avail_rxqs respectively.
The aforementioned bitmaps and arrays should be allocated dynamically,
because the number of queues supported by a PF is only available once
function capabilities have been queried. The current static allocation
consumes way more memory than required.
This patch removes the DECLARE_BITMAP for avail_txqs and avail_rxqs
and instead uses bitmap_zalloc to allocate the bitmaps during init.
Similarly txq_map and rxq_map are now allocated in ice_vsi_alloc_arrays.
As a result ICE_MAX_TXQS and ICE_MAX_RXQS defines are no longer needed.
Also as txq_map and rxq_map are now allocated and freed, some code
reordering was required in ice_vsi_rebuild for correct functioning.

Refactor the queue handling functions that are going through queue
arrays in a way that the logic done for a single queue is pulled out and
it will be called for each ring when traversing ring array. This implies
that when disabling Tx rings we won't fill up q_ids, q_teids and
q_handles arrays. Drop also 'offset' parameter; the value from vsi's
txq_map is stored in ring->reg_idx and that drops the need for mentioned
parameter. Introduce the ice_vsi_cfg_txq, ice_vsi_stop_tx_ring and
ice_vsi_ctrl_rx_ring that are the functions with pulled out logic.
There's several Tx queue meta data (q_id, q_handle, q_teid and other)
that need to be set up during Tx queue disablement, so let's as well add
a helper structure that wraps it up and a function that will be filling
it up.

VSI, especially VF could request to add or remove filter for another VSI,
driver should really guide such request and disallow it.
However, instead of returning error for such malicious request, driver
can simply return success.
In addition, we are not tracking number of MAC filters configured per
VF correctly - and this leads to issue updating VF MAC filters whenever
they were removed and re-configured via bringing VF interface down and
up. Also, since VF could send request to update multiple MAC filters at
once, driver should program those filters individually in the switch, in
order to determine which action resulted to error, and communicate
accordingly to the VF.
So, with this changes, we now track number of filters added right from
when VF resources allocation is done, and could properly add filters for
both trusted and non_trusted VFs, without MAC filters mis-match issue in
the switch...
Also refactor code, so that driver can use new function to add or remove
MAC filters.

The virtchnl interface provides a mechanism for a VF driver to request
head writeback support. This feature is deprecated as of AVF 1.0, but
older versions of a VF driver may still attempt to request the mode.
Since the ice hardware does not support head writeback, we should not
accept Tx queue configuration which attempts to enable it.
Currently, the driver simply assumes that the headwb_enabled bit will
never be set.
If a VF driver does request head writeback, the configuration will
return successfully, even though head writeback is not enabled. This
leaves the VF driver in a non functional state since it is assuming to
be operating in head writeback mode.

Currently we use the ICE_MBXQ_LEN for both the Mailbox send and receive
queues that are used to communicate with VFs. This is fine for the send
queue because the PF driver will lock the queue for every single send,
but for the Mailbox receive queue every VF is posting to its Mailbox
send queue and the hardware is then handing the message to the PF on its
Mailbox receive queue. This becomes a problem with many VFs because it
seems to overburden the Mailbox receive queue on the PF. Fix this by
increasing the Mailbox receive queue for the PF to 512 entries.
The number 512 was determined based on the number of VFs supported by
the device. We can have a total of 256 VFs so in the worst case this
allows the VFs to put 2 messages in the PFs Mailbox receive queue at the

spin for longer than necessary in the __IAVF_STARTUP state. Sometimes
it causes the AVF to go into the __IAVF_COMM_FAILED, which may retrigger
the __IAVF_STARTUP state. Try to reduce the chance of this happening by
removing unnecessary wait times in VF bringup/resets.

During rebuild ice_ena_vsi() is called to recover the VSI state.
This function assumes the PF VSI is always to be enabled, however,
it's possible that during reset/rebuild the interface can be
brought down. If this occurs, we can attempt to bring up the PF
VSI on a downed interface which can lead to various crashes. If
the interface is not running, do not bring up the associated VSI.
