commit d1c9da9e4c938e8bbf8b0ef9e5772b97db5639e9 upstream.
The implementation of embedding WTBL update inside the STA_REC update is buggy on the MT7615 v2 firmware. This leads to connection issues after a station has connected and disconnected again.
Switch to the v1 MCU API ops, since they have received much more testing and should be more stable.
On MT7622 and later, the v2 API is more actively used, so we should keep using it as well.
