mac80211: move MU_MIMO_OWNER flag to ieee80211_vif
Drivers may need to track which vif is using VHT MU-MIMO. Move the flag indicationg the ownership of MU_MIMO to ieee80211_vif. Signed-off-by: Sara Sharon <sara.sharon@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
