rt2x00: Store queue idx and entry idx in data_ring and data_entry
Store the queue idx inside structure data_ring Store the entry idx inside structure data_entry This saves us a few calls to ARRAY_INDEX() which is now unused. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
