When the fcsfail filter is enabled the hardware passes frames with a bad FCS up to the driver, but mt76x02_mac_process_rx() never checks MT_RXINFO_CRCERR and hands them to mac80211 without RX_FLAG_FAILED_FCS_CRC. In monitor mode the radiotap flags byte then never gets IEEE80211_RADIOTAP_F_BADFCS set and corrupted frames cannot be told apart from clean ones. Set RX_FLAG_FAILED_FCS_CRC from the descriptor CRC error bit, matching mt7603, mt7615, mt7915, mt7921, mt7925 and mt7996.
