Commit 3a25a8c ("mac80211: add improved HW queue control")
added support for offchannel queue mapping. However, this
mapping is only valid when the driver supports
IEEE80211_HW_QUEUE_CONTROL.
Check whether the driver supports IEEE80211_HW_QUEUE_CONTROL
before setting the hw_queue to the mapped offchannel queue.
(This patch doesn't have any actual effect, because
hw_queue is overridden in ieee80211_tx() anyway,
so this is merely some cleanup)

Linus reported that due to mac80211 failing to register
the device (due to WoWLAN) his machine crashed etc. as
we double-freed the vmalloc() firmware area. His patch
to fix it was very similar to this one but I noticed
that there's another bug in the area: we complete the
completion before starting, so since we're running in
a work struct context stop() could be called while in
the middle of start() which will almost certainly lead
to issues.
Make a modification similar to his to avoid the double-
free but also move the completion to another spot so it
is only done after start() either finished or failed so
that stop() can have a consistent state.

In some multi role scenarios the driver might send multi
roc requests without sending a croc first, the fw queues
those requests and starts service the next roc request as
soon as the driver sends a croc for the previous one. So,
if the fw rocs on channel X and driver asks to roc also
on channel Y, the fw will not start service Y (and will
not send roc complete event for this request) until the
driver releases the fw with croc X.
