vhost-test: drop flush after vhost_dev_cleanup

The flush after vhost_dev_cleanup is not needed because:

1. It doesn't do anything. vhost_dev_cleanup will stop the worker thread
so the flush call will just return since the worker has not device.

2. It's not needed. The comment about jobs re-queueing themselves does
not look correct because handle_vq does not requeue work.
