docs: cgroup-v1: Update page cache removal functions 

Commit 452e9e6992 ("filemap: Add filemap_remove_folio and
__filemap_remove_folio") reimplemented __delete_from_page_cache() as
__filemap_remove_folio() and delete_from_page_cache() as
filemap_remove_folio().  The compatibility wrappers were finally removed
in ece62684dc ("hugetlbfs: convert hugetlb_delete_from_page_cache() to
use folios") and 6ffcd825e7 ("mm: Remove __delete_from_page_cache()").

Update the remaining references to dead functions in the memcg
implementation memo.

__filemap_remove_folio() is called by filemap_remove_folio()
and __remove_mapping().
