rt2x00: Increase queue size

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

/**
* DOC: Number of entries per queue
*
* After research it was concluded that 12 entries in a RX and TX
* queue would be sufficient. Although this is almost one third of
* the amount the legacy driver allocated, the queues aren't getting
* filled to the maximum even when working with the maximum rate.
* Under normal load without fragmentation 12 entries are sufficient
* without the queue being filled up to the maximum. When using fragmentation
* and the queue threshold code we need to add some additional margins to
* 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.
