mac80211: fix queue handling crash
The code I added in "mac80211: don't start new netdev queues if driver stopped" crashes for monitor and AP VLAN interfaces because while they have a netdev, they don't have queues set up by the driver. To fix the crash, exclude these from queue accounting here and just start their netdev queues unconditionally. For monitor, this is the best we can do, as we can redirect frames there to any other interface and don't know which one that will since it can be different for each frame. For AP VLAN interfaces, we can do better later and actually properly track the queue status. Not doing this is really a separate bug though.
