wext: really disassociate (set random SSID)

Browse source 
Really disassociate when tearing stuff down; drivers may sometimes
(legally) keep trying to reassociate unless the BSSID is unlocked.  If
the SSID is unlocked too, under WEXT drivers are able to pick an SSID to
associate, so kill that behavior by setting a bogus SSID.  Unfortunately
WEXT doesn't provide an easy method to say "stop whatever doing and just
idle".
