4.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Andrei Otcheretianski <andrei.otcheretianski@xxxxxxxxx>
commit a64cba3c5330704a034bd3179270b8d04daf6987 upstream.
Local request to deauthenticate wasn't handled while associating, thus
the association could continue even when the user space required to
disconnect.
