    Delete port created by kuryr

    In current code, we get the port's subnet by checking the
    subnet's subnetpool_id equal with the given PoolID, but in
    existing environment, the subnet may lack subnetpool_id,
    hence we will not get the port's subnet and leaves the
    kuryr-libnetwork port undeleted.

    This patch checks the port's device owner and determines
    the given POOL's subnet_id and ip_address is equal to
    port's fixed_ips attribute.
