virtio: remove ioeventfd_disabled altogether

Now that there is not anymore a switch from the generic ioeventfd handler
to the dataplane handler, virtio_bus_set_host_notifier(assign=true) is
always called with !bus->ioeventfd_started, hence virtio_bus_stop_ioeventfd
does nothing in this case.  Move the invocation to vhost.c, which is the
only place that needs it.
