[dpdk-dev] [PATCH] vhost user: unlink sockaddr when poll sched fails

[Gellert Babel <gellert.babel@ericsson.com>]

From: Jan Wickbom <jan.wickbom@ericsson.com>

Issue:

Vhost user socket addresses left in /var/run/openvswitch.
This will lead to failure to add vhost user ports with names that
already exist in this directory.

When there is a failure to add a vhost user socket file descriptor to
the file descriptor set using fdset_add() in
rte_vhost_driver_register() the address bound to the socket is not
released.

Solution:
Add unlink of the file path corresponding to the socket address.
