[PATCH 2/3] cfg80211: fix nl80211 disconnected events

[Johannes Berg <johannes@sipsolutions.net>]

When reporting a disconnection to userspace, we try
to report whether it was from the AP or by our own
choice. However, we misreported a broadcast deauth
or disassoc as being by own choice, which is wrong.
Fix this by checking the sender address instead of
the destination address.
