Subject: [PATCH] cfg80211: don't look at wdev->ssid for giwessid
This variable is only used internally, _while_ connected.
If we use it, the sequence
# iwconfig wlan1 essid foo
<connects>
# iwconfig wlan1 essid ""
<disconnects>
# iwconfig
will still display "foo" as the SSID afterwards, which
is obviously quite bogus. Fix this by only displaying
the wext SSID, if present.
