netdev-dpdk: Clean-up after vHost User port delete

Unregister and delete the socket associated with a vhost-user port when the port is deleted and/or the switch is brought down. Do not delete the socket if the vhost-user device is still attached to the guest. Signed-off-by: Ciara Loftus <[email protected]> Acked-by: Daniele Di Proietto <[email protected]>
