The RX data queue is initialized already when the rt2800_usb_enable_radio() 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->rx->limit value allows us to get rid of a superfluous pointer dereference.
