Subject: [PATCH 4/6] vhost_vsock: simplify vhost_vsock_flush()

vhost_vsock_flush() calls vhost_work_dev_flush(vsock->vqs[i].poll.dev)
before vhost_work_dev_flush(&vsock->dev). This seems pointless
as vsock->vqs[i].poll.dev is the same as &vsock->dev and several flushes
in a row doesn't do anything useful, one is just enough.
