[PATCH] mac80211: probe for hidden SSIDs in pre-auth scan

["John W. Linville" <linville@tuxdriver.com>]

From: John W. Linville <linville@tuxdriver.com>

Probe for hidden SSIDs if initiating pre-authentication scan and SSID
is set for STA interface.

The ternary conditionals are a bit ugly.  I guess I could recode it
with temp vars initialized before calling ieee80211_sta_start_scan.

Any other complaints?
