[PATCH] assoc response status code in case of failure

Thu Mar 3 10:48:09 PST 2016
From: Naveen Singh <nasingh at google.com>
Assoc response with status code other than 0 is now notified
over DBUS as a part of PropertiesChanged Signal. This can be used
by application in case AP is denying association with status code 17
(band steering) so that it does not interfere in the BSSID selection
logic of wpa_supplicant.
