wifi: mt76: mt7996: add missing check for rx wcid entries

Browse Source 
Non-station wcid entries must not be passed to the rx functions.
In case of the global wcid entry, it could even lead to corruption in the wcid
array due to pointer being casted to struct mt7996_sta_link using container_of.

Fixes: 7464b12b7d92 ("wifi: mt76: mt7996: rework mt7996_rx_get_wcid to support MLO")
