Wrong port id in fip-show of floatingip assigned to virtual-ip

In case of floating ip on the Virtual-ip, svc-monitor will link floating ip to
"right" interface of service VMs launched by ha-proxy service instance.

Ignore such VMI while walking the vmi_ref from floatingip object.
This is done based on the service interface type of the interface.
Right interface of the service instance will have this property value set to "right"
