[dpdk-dev] [PATCH] vhost: fix passing destroyed device to destroy callback

[Ilya Maximets <i.maximets@samsung.com>]

Application should be able to obtain information like 'ifname' from
the 'vid' passed to 'destroy_connection' callback. Currently, all the
API calls with passed 'vid' fails with 'device not found'.

Fixes: efba12a78ddf ("vhost: add user callbacks for socket open/close")
