iwlwifi: support new queue allocation command
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.
