mac80211: always allow calling ieee80211_connection_loss()
With multi-channel, there's a corner case where a driver doesn't receive a beacon soon enough to be able to sync its timers with the AP. In this case, the only recovery (after trying again) is to disconnect from the AP. Allow calling ieee80211_connection_loss() for such cases. To make that possible, modify the work function to not rely on the IEEE80211_HW_CONNECTION_MONITOR flag but use new state kept in the interface instead.
