mac80211: fix two remote exploits

in mac80211, which is due to some code shuffling I did
that ended up changing the order in which things were
done -- this was in

mac80211: RX aggregation: clean up stop session
The problem is that the BUG_ON moved before the various
checks, and as such can be triggered.
As the comment indicates, the BUG_ON can be removed since
the ampdu_action callback must already exist when the
state is OPERATIONAL.
A similar code path leads to a WARN_ON in
ieee80211_stop_tx_ba_session, which can also be removed.
