We forget to add the suffix to the workingset_restore string, so
fix it. And also update the documentation of cgroup-v2.rst.

Fixes: 170b04b7ae49 ("mm/workingset: prepare the workingset detection infrastructure for anon LRU")
Signed-off-by: Muchun Song <songmuchun@bytedance.com>
---
 changelog in v6:
 1. There is no version of v1-v5.
