In vDPA, GET_VRING_BASE does not stop the queried vring, which is why SUSPEND was introduced so that the returned index would be stable. In vhost-user, it does stop the vring, so under the same reasoning, it can get away without SUSPEND. Still, we do want to clarify that if the device is completely stopped, i.e. all vrings are stopped, the back-end should cease to modify any state relating to the guest. Do this by calling it "suspended".
