mac80211: use synchronize_net() on key destroying
__ieee80211_key_destroy() calls synchronize_rcu() in
order to sync the tx path before destroying the key.
However, synching the tx path can be done with
synchronize_net() as well, which is usually faster
(the timing might be important for roaming scenarios).
