  Log Message:
  -----------
  netdev-dpdk: Unlink vhost-user sockets on fatal signals.

While killing OVS may not call rte_vhost_driver_unregister()
for vhost-user ports. As a result corresponding socket will
remain in a system and opening of that port after restart
will fail.

(Even after this patch this remains a problem for signals
that OVS does not or cannot catch, such as SIGSEGV and
SIGKILL.)
