rt2x00: Don't switch to antenna with low rssi
When rssi_a > rssi_b is true and the current antenna was already antenna A, then rt2x00 incorrectly jumped to antenna B. Also don't configure the antenna when there has been no change in the antenna setup. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
