nl80211: Use device AP SME capability

Browse source 
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.
