Commit [3469adb3: fix potential NULL pointer dereference] introduced
a check of msg_ind allocation, but omitted allocation of msg_ind->msg.
Moreover, it introduced two if statements, which looked a bit clunky.
This commit moves allocation code outside of the critical section so
there's no need to dance around mutex_unlock, and adds the missing
allocation check.

Some cards don't update the PISR properly when all SISR bits
for Tx interrupts are being cleared and as a result we get
interrupt storm. Since we handle all tx queues all together
(so we don't really use the SISR bits to do per-queue interrupt
handling), we can manualy update PISR by doing a write-to-clear
on its Tx interrupt bits.

The Buffalo device WZR-HP-G450H uses the index 3 for TX gain,
which is set to the high_power table currently. Later variants
of the router use the same index, but instead refer to the
low_ob_db gain table. This is not handled in the driver since
there is no way to distinguish board revisions and the high_power
table is used (incorrectly) for the newer variants.
By default, devices based on AR9300 using the TX gain index 3 have
to use the high_power table. To make sure that WZR-HP-G450H is not
broken when the high_power table is updated, use a separate array
based on information obtained from the platform data.
The current situation where only the original variant of WZR-HP-G450H
works properly stays unchanged.

As it stands dynamic user regulatory domain support is
only possible for a few programmed regulatory domains as
a few countries do not allow for this.
The existing code however only would take advantage of
the feature if a custom world regulatory domain is used
though as that's when we clear beconing flags. We need
to lift this restriction as otherwise this feature is
pointless.

The routine ath_reg_apply_active_scan_flags() can be a bit
hard to read, this cleans it up by adding helpers for the
two cases of clearing IR flags or adding them. This approach
also makes no assumptions on the index of channels 12 and 13
so it should be portable accross different drivers.

The existing logic removes the passive scan flag from
channels 12 and 13 when a regulatory hint coming from
something other than a country IE has been passed. This
is incorrect, the original intention was to ensure we
always have passive scan enabled for these two channels
