Peter ChiuandFelix Fietkau 37955a4d08 wifi: mt76: mt7996: use hweight16 to get correct tx antenna
The chainmask is u16 so using hweight8 cannot get correct tx_ant.
Without this patch, the tx_ant of band 2 would be -1 and lead to the
following issue:
BUG: KASAN: stack-out-of-bounds in mt7996_mcu_add_sta+0x12e0/0x16e0 [mt7996e]
