In independent repeater scenario when STA connects to root AP on different channel as that of AP Vdevs, then txCSA is used to move the AP vdevs to the new channel using FW_VDEV_RESTART. If a ML-AP vdev is stuck in MLO_SYNC_WAIT state, then TxCSA is not processed which would lead to MVR timeout. Add change to handle FW_VDEV_RESTART event in SYNC_WAIT.
