mac80211: add explicit monitor interface if needed
The queue mapping redesign that I'm planning to do will break pure injection unless we handle monitor interfaces explicitly. One possible option would be to have the driver tell mac80211 about monitor mode queues etc., but that would duplicate the API since we already need to have queue assignments handled per virtual interface. So in order to solve this, have a virtual monitor interface that is added whenever all active vifs are monitors. We could also use the state of one of the monitor interfaces, but managing that would be complicated, so allocate separate state.
