Flush to guarantee no workers are running when suspend returns,
for vdpa, vdpa_sim, and vduse. (mlx5 already does so, via the path
mlx5_vdpa_suspend -> unregister_link_notifier -> flush_workqueue.)
Changes in V2:
- renamed "vduse: suspend" (was vduse: flush workers on suspend)
- call vhost_dev_flush unconditionally in "vhost-vdpa: flush workers on suspend"
Changes in v3:
- rewrote vdpa_sim patch
