cfg80211/mac80211: move combination check to mac80211 for ibss
Now that mac80211 can check the interface combinations itself, move the combinations check from cfg80211 to mac80211 when joining an IBSS. Signed-off-by: Luciano Coelho <luciano.coelho@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
