mac80211: update A-MPDU flag on tx dequeue 

The sequence number counter is used to derive the starting sequence
number. Since that counter is updated on tx dequeue, the A-MPDU flag
needs to be up to date at the tme of dequeue as well.

This patch prevents sending more A-MPDU frames after the session has
been terminated and also ensures that aggregation starts right after the
session has been established
