mac80211: Remove superfluous if clause
ieee80211_rx_h_check returned RX_DROP_MONITOR in case the if statement in question was true but the same return value is also used directly after the if clause. Hence, we can just drop the whole if clause and as such simplify the code. Signed-off-by: Helmut Schaa <helmut.schaa@googlemail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
