wifi: mt76: decode the full VHT Rx STBC capability field

Browse Source 
The Rx STBC subfield of the VHT capabilities is a 3-bit cumulative value,
but the driver only tested the RXSTBC_1 bit when advertising the peer's
Rx STBC support to firmware. A peer reporting Rx STBC of 2, 3 or 4 has
that bit clear, so STBC was never used towards it. Test the full
IEEE80211_VHT_CAP_RXSTBC_MASK, matching the HT path.
