mm: memcg: fix memcg file_dirty numa stat
commit 8a8792f600abacd7e1b9bb667759dca1c153f64c upstream.
The kernel updates the per-node NR_FILE_DIRTY stats on page migration
but not the memcg numa stats.
That was not an issue until recently the commit 5f9a4f4a7096 ("mm:
memcontrol: add the missing numa_stat interface for cgroup v2") exposed
numa stats for the memcg.
So fix the file_dirty per-memcg numa stat.
