    [OVN] Match LSP_TYPE_VIRTUAL in PortBindingUpdateVirtualPortsEvent

    With newer versions of OVN, port bindings are removed and added
    for both virtual ports and container ports (aka trunk ports in
    Neutron world)[1][2].

    With this, Neutron recently landed a change in order to handle
    virtual ports for the update/delete steps[3], however, this has
    resulted in unexpected behaviour where the binding information
    is wiped for trunk ports, then subsequently removed on the
    next maintenance run.

    We should make sure that we only have row deletes for
    virtual ports specifically rather than all ports.
