wifi: mt76: mt7915: avoid nss underflow in mt7915_mcu_get_sta_nss

Browse source

If a peer's VHT/HE MCS map has no supported spatial stream (all fields
0x3), the loop exits with nss == 0 and the function returned (u8)-1 (255),
which was then written into the firmware sta_rec_bf beamforming fields.
Clamp the result to 0.
