mac80211: use offchannel queue only when supported
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)
