[PATCH 4/4] mac80211: make active monitor injection work w/ HW queue

[Johannes Berg <johannes@sipsolutions.net>]

From: Johannes Berg <johannes.berg@intel.com>

When a driver (like hwsim) uses HW queue control an
active monitor vif needs to be used for the queues,
make the code do that. Otherwise we'd bail out and
drop the frames.
