Subject: mac80211: fix notify_mac function
From: Johannes Berg <johannes@xxxxxxxxxxxxxxxx>
The ieee80211_notify_mac() function uses ieee80211_sta_req_auth() which in
turn calls ieee80211_set_disassoc() which calls a few functions that need
to be able to sleep, so ieee80211_notify_mac() cannot use RCU locking for
the interface list and must use rtnl locking instead.
