rt2x00: Initialize txop during conf_tx() callback
The txop parameter is supported by rt61pci and rt73usb, and thus should be written to the register instead of using the fixed value set during initialization. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
