[RFC PATCH v4 04/20] vhost: Make vhost_virtqueue_{start,stop} public

["Eugenio Pérez" <eperezma@redhat.com>]

The easier way to reset vhost behavior after enabling shadow virtqueue
is to call vhost_virtqueue_start. Also, vhost_virtqueue_stop provides
the simmetrical call to it, and it will be used.
