mac80211: don't delay station destruction
If we can assume that stations are never referenced by the driver after sta_state returns (and this is true since the previous iwlmvm patch and for all other drivers) then we don't need to delay station destruction, and don't need to play tricks with rcu_barrier() etc. This should speed up some scenarios like hostapd shutdown.
