[PATCH v2 2/2] vhost: release virtqueue objects in error path

[P J P <ppandit@redhat.com>]

From: Prasad Pandit <pjp@fedoraproject.org>

vhost_dev_start function does not release virtqueue objects when
event_notifier_init() function fails. Release virtqueue objects
and log a message about function failure.
