[PATCH mt76-next 07/29] wifi: mt76: fix ER-SU 106-tone RU check in RX rate decode

[Felix Fietkau <nbd@nbd.name>]

MT_PHY_TYPE_HE_EXT_SU is an enum value (9), not a bit flag, so the
bitwise test "*mode & MT_PHY_TYPE_HE_EXT_SU" also matches OFDM, HT-GF and
several HE/EHT modes. Only genuine ER-SU should be classified as a
106-tone RU at 40 MHz; use an equality comparison.

Fixes: 98686cd21624 ("wifi: mt76: mt7996: add driver for MediaTek Wi-Fi 7 (802.11be) devices")
Fixes: d832f5e73815 ("mt76: connac: move mt76_connac2_mac_fill_rx_rate in connac module")
