mac80211: disable HT advertising unless AP supports it
If the AP doesn't support HT, or more importantly if it does but we have to disable it because its IEs are broken, don't advertise HT support in our association request. Otherwise, we configure our channel to be a 20 MHz non-HT channel but the AP might still think we support HT, or even 40 MHz. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
