wifi: mt76: add wcid publish check in mt76_sta_add

Since mt7925_mac_sta_add publishes wcid, add publish check in mt76_sta_add

to avoid reinitializing the wcid->poll_list.

Found dev->sta_poll_list corruption when using mt7925 and 7.1-rc4.

According to the corruption information, prev->next was changed to itself.

wlan0: disconnect from AP 90:fb:5d:94:8b:e3 for new auth to 90:fb:5d:94:8b:e2

wlan0: authenticate with 90:fb:5d:94:8b:e2 (local address=84:9e:56:9c:7e:6b)

wlan0: send auth to 90:fb:5d:94:8b:e2 (try 1/3)

slab kmalloc-8k start ffff8c80958a6000 pointer offset 4160 size 8192

list_add corruption. prev->next should be next (ffff8c808a7488f8), but was ffff8c80958a7040. (prev=ffff8c80958a7040).
