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.

/**
* 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.
