realtek: dsa: Sync CIST with MSTI state for unbridged ports
The VLANs and their MSTIs are shared on the realtek switch HW between
bridged and unbridged ports. But the MSTI state cannot be updated for an
unbridged port via DSA. To ensure that the port is still configured
correctly after leaving a bridge, the CIST state updates via DSA must also
be propagated to the MSTI states.
