mm/huge_memory: convert split_huge_pages_pid() from follow_page() to folio_walk
Let's remove yet another follow_page() user. Note that we have to do the
split without holding the PTL, after folio_walk_end(). We don't care
about losing the secretmem check in follow_page().
[david@redhat.com: teach can_split_folio() that we are not holding an additional reference]
