From: Reinette Chatre <reinette.chatre@xxxxxxxxx>
* Rename maximum number of queue (TFD_QUEUE_MAX) to IWL39_NUM_QUEUES to
be consistent with rest of iwlwifi.
* Remove unused defines.
* Fix loops that iterate over number of TX queues to stop when maximum is reached
(currently it is maximum + 1).
* Remove queues_num module parameter as it is not used.
