Newer firmware versions will support a new queue allocation
command, in order to deal with MLD where multiple stations
are used for a single queue. Add support for the new command.

This requires some refactoring of the queue allocation API,
which now gets
 - the station mask instead of the station ID
 - the flags without the "enable" flag, since that's no longer
   used in the new API

Additionally, this new API now requires that we remove queues
before removing a station, the firmware will no longer do that
internally. Also add support for that.
