netdev: always register for single CQM threshold

Browse Source 
If the extended feature for CQM levels was not supported no CQM
registration would happen, not even for a single level. This
caused IWD to completely lose the ability to roam since it would
only get notified when the kernel was disconnecting, around -90
dBm, not giving IWD enough time to roam.

Instead if the extended feature is not supported we can still
register for the event, just without multiple signal levels.
