mac80211: always use wpa_supplicant for client connections (patch by Stijn Tintel)
Since client mode in mac80211is unreliable without using wpa_supplicant, it would be better to enable wpa_supplicant by default. With this patch, wpa_supplicant will always be used for mac80211-based drivers in client mode. This will break client mode for images that don't include wpa_supplicant or wpad, so maybe I need to add a check somewhere to see if wpa_supplicant is available, and show the user a warning if he tries client mode without wpa_supplicant. Suggestions on where to add this check are welcome. Tested with ath5k in client mode on open and wpa2-psk network, and tested on my ath9k based AP as well to make sure it doesn't break AP mode. SVN-Revision: 19718
