Until hostapd is able to restart service on a channel (e.g. by reacting
to an event that a DFS non-occupancy period is over), better shut down
hostapd when no channel is available anymore.

The current behaviour, disabling the interface, will just lead to
hostapd hanging without recovering frmo this state. If hostapd shuts
down, userspace can at least work around and restart hostapd when
channels are available again.
