stop sched scan isn't an immediate operation
and we need to wait for PERIODIC_SCAN_COMPLETE_EVENT_ID
after sending a stop before changing internal state
and notifying upper layers.
Not doing this caused problems when canceling an existing sched
scan and immediately requesting to start a new one
with a different configuration as the FW was still
in the middle of the previous sched scan.

Couple them together by introducing new wl12xx_start_dev

Instead of doing passive scans in active states, we now skip active

Implement support for filtering in scheduled scans.
With this commit we now use the match sets passed by cfg80211 to

The wl12xx firmwares support multiple SSIDs in a single sched_scan
run. This patch implements support for it.
We use three different types os sched_scan: FILTER_ANY (ie. not
filtering, only wildcard SSID in the probe_reqs); FILTER_LIST (ie. send out
probe_reqs with the specified SSIDs and only report if they are
found); and FILTER_DISABLED (ie. send out probe_reqs with the
specified SSIDs, but report anything found).
Since we still don't have proper filter support in nl80211/cfg80211
yet, we cannot use filters when the wildcard SSID is used. Thus, we
will not filter anything if the wildcard SSID is specified.

The ROC command asks the fw stay on the channel of the given
hlid. it currently has 2 primary functions:
1. Allow tx/rx from the device role.
In order to tx/rx packets while the stations is not associated
(e.g. auth req/resp), the device role has to be used, along
with ROC on its link.
Keep the logic similiar to the one used in dummy_join. However,
since we can't scan while we ROC, we add CROC before starting
a scan, and ROC again (if needed) on scan complete.
2. Keeping the antenna for a specific link.
We ROC until the connection was completed (after EAPOLs exchange)
in order to prevent BT coex operations from taking the antenna
and failing the connection (after this stage, psm can be used).
During association, we ROC on the station role, and then CROC
the device role, thus assuring being ROC during all the connection
process.
Delete the WL1271_FLAG_JOINED flag, and use a roc bitmap
to indicate what roles are currently ROCed.
Add wl12xx_roc/croc functions in order to wrap the roc/croc
commands while taking care of the roc bitmap.
The current ROC/CROC state-machine is a bit complicated. In
the future we'll probably want to use wpa_supplicant to control
the ROC during connection.

Fix kernel oops when trying to use passive scheduled scans. The
reason was that in passive scans there are no SSIDs, so there was a
NULL pointer dereference.
To solve the problem, we now check the number of SSIDs provided in the
sched_scan request and only access the list if there's one or more
(ie. passive scan is not forced). We also force all the channels to
be passive by adding the IEEE80211_CHAN_PASSIVE_SCAN flag locally
before the checks in the wl1271_scan_get_sched_scan_channels()
function.

thus far has been an empty one, without the SSID IE and without supported rate
IEs. This causes problems with some AP's.
