It used to be done at vhost_vdpa_svq_cleanup, since a device couldn't
switch to SVQ mode dynamically. Now that we need to fetch the state and
trust SVQ will not modify guest's used_idx at migration, stop
effectively SVQ at suspend time, as a real device would do.
Leaving old vhost_svq_stop call at vhost_vdpa_svq_cleanup, as its
supported to call it many times and it follows other operations that are
called redundantly there too:
* vhost_vdpa_host_notifiers_uninit
* memory_listener_unregister
