Since we introduce folio, replace isolate_lru_page() with
folio_isolate_lru().

This seems like a good patch to copy to linux-mm - done now.

The patch perhaps is a closer match to what's in linux-next, but it
seems that, if we're going to update this document, we should reflect
the use folios throughout?

Most of the current users of migrate_pages() still use isolate_lru_page()
so I think that updating page_migration.rst to folios is premature.
But when we do the update it also should include the translations.

It's a slim majority -- 9 of isolate_lru_pages() and 7 of
folio_isolate_lru().  I don't think that changing the documentation is
premature; we should document the functions we want people to use.
I'd be surprised if isolate_lru_pages() still existed in six months.
