mac80211: fix direct probe loop on ieee80211_work_purge
If authentication has already been performed when the WLAN interface is
stopped, (sometimes) the ieee80211_work_purge would corrupt some
ieee80211_work-structures. The outcome is this (cleaned up):
[ 2252.398681] WARNING: at net/mac80211/work.c:995 ieee80211_work_purge
[ 2252.466430] Backtrace:
[ 2252.529266] (ieee80211_work_purge+0x0/0xcc [mac80211])
[ 2252.546875] (ieee80211_stop+0x0/0x4c0 [mac80211])
Additionally, one would get this, going on regarless of the WLAN interface
state, going on forever:
