nl80211: Use device AP SME capability
This changes the auto-detection of whether or not the device contains the AP SME away from monitor interface addition failing to the explicit attribute in nl80211. Keep the old auto-detection for a little while so that ath6kl isn't broken right away. Signed-hostap: Johannes Berg <johannes.berg@intel.com>
