Add back the previously removed cgroup function to support the kthread
The biggest change for this part is in vhost_attach_cgroups() and
vhost_attach_task_to_cgroups().

Reuse the function __vhost_worker_flush, but in this situation, the
attachment_cnt is 0. Therefore, add a boolean to disable this check.

How about just tweaking its value to INT_MAX so we can avoid this new parameter?

Thanks
