rt2x00: rt61pci: use rt2x00dev->tx->limit

Browse Source 
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.
