Since mesh powersaving was added, pending bcast/mcast frames may go out the
CAB queue now. Unfortunately, the queue was only set up for AP mode, so we
would try to tx on the IEEE80211_INVAL_HW_QUEUE. Allow cab_queue for mesh
interfaces as well.
Fixes the following warning (or crash without MAC80211_VERBOSE_DEBUG):
