wifi: mt76: mt7925: fix msg len mismatch between driver and firmware

Browse source

The mt7925_tx_power_limit_tlv struct begins with a 4-byte rsv[] field
that acts as a UNI command header prefix. The firmware dispatcher did
not use the 4-byte rsv[] and will only check the payloads after the
4-byte rsv[] As a result, the total message length minus the 4-byte
prefix. Fix this by setting len to msg_len - 4.
