cfg80211: fix wext stats
Instead of using the wext BSSID which may be NULL if you haven't explicitly set one, we should instead use the current_bss pointer -- if that's NULL we aren't connected anyway. Fixes missing signal quality output reported to me internally at Intel. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
