wifi: mt76: fix 4th chain ACK RSSI bitmask in sta_poll
The per-chain response-frame RSSI values are packed one per byte, but the
4th chain was extracted with GENMASK(31, 14) instead of GENMASK(31, 24).
The wrong mask overlaps chains 1-3 and shifts by 14, producing a garbage
chain-3 value that corrupts ack_signal/avg_ack_signal on 4x4 radios.
Extract the correct byte.
