rt2x00: rt2x00queue: add priv_size field to struct data_queue
Add a new field into struct data_queue and store the size of the per-queue_entry private data in that. Additionally, use the new field in the rt2x00queue_alloc_entries function to compute the size of the queue entries for a given queue. The patch does not change the current behaviour but makes it possible to remove the queue_desc parameter of the rt2x00queue_alloc_entries function. That will be done by a subsequent patch.
