rt2x00: rt2800pci: use rt2x00dev->tx->limit
The TX data queue is initialized already when
the rt2800pci_txstatus_interrupt() 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.
