ath9k_common (used by ath9k and ath9k_htc) trusts the frames
blessed by hardware as OK are infact correct even if the rate
seen by the driver is unrecognized. ath9k_common just treats
these frames in mac80211 as frames as frames under 1 mbps rate.
It seems this might not be the best thing to do as other parts of
the frame might not be valid so just drop these frames for now.
