mac80211: clean up sta_info_destroy() users wrt. RCU/locking

Browse Source 
Calling sta_info_destroy() doesn't require RCU-synchronisation
before-hand because it does that internally. However, it does
require rtnl-locking so insert that where necessary.

Also clean up the code doing it internally to be a bit clearer and
not synchronize twice if keys are configured.
