mac80211: Check port authorization in the ieee80211_tx_dequeue() case
commit ce2e1ca703071723ca2dd94d492a5ab6d15050da upstream.
mac80211 used to check port authorization in the Data frame enqueue case
when going through start_xmit(). However, that authorization status may
change while the frame is waiting in a queue. Add a similar check in the
dequeue case to avoid sending previously accepted frames after
authorization change. This provides additional protection against
potential leaking of frames after a station has been disconnected and
the keys for it are being removed.
