mac80211: disassociate prior to unlinking AP/station
This patch reorders calls during disassociation in ieee80211_set_disassoc function. Since sta_info_unlink calls sta_notify(REMOVE) it will remove the station representing AP from the driver before it has disassociated from it using bss_info_changed callback.
