northd: handle virtual lport type update

ovn-northd re-create sbrec row for lport of type
virtual when the type explicitly updated in NBDB.

This approach was applied to handle container lport
type updates and avoid handling issues in the ovn-controller,
this patch expanded that approach to handle lport of type
virtual in the same way.
