rt2x00: Increase queue size 



Without the preallocated DMA we can now safely increase
the queue size withotu negative impact on the memory
requirements of rt2x00.

 * After research it was concluded that 12 entries in a RX and TX

 * Under normal load without fragmentation 12 entries are sufficient

 * queue would be sufficient. Although this is almost one third of

 * the amount the legacy driver allocated, the queues aren't getting

 * and the queue threshold code we need to add some additional margins to

 * filled to the maximum even when working with the maximum rate.

 * make sure the queue will never (or only under extreme load) fill up

 * completely.

 * Since we don't use preallocated DMA having a large number of queue entries

 * will have only minimal impact on the memory requirements for the queue.
