rt2x00: rt61pci: use rt2x00dev->tx->limit
The TX data queue is initialized already when the rt61pci_txdone() function is called. Fetch the number of the queue entries from that instead of using the entry_num field of the data queue descriptor. The two values are the same, and the use of the rt2x00dev->tx->limit value allows us to get rid of a superfluous pointer dereference.
