mm: add folio_add_new_anon_rmap()
In contrast to other rmap functions, page_add_new_anon_rmap() is always
called with a freshly allocated page. That means it can't be called with
a tail page. Turn page_add_new_anon_rmap() into folio_add_new_anon_rmap()
and add a page_add_new_anon_rmap() wrapper. Callers can be converted
individually.
[akpm@linux-foundation.org: fix NOMMU build. page_add_new_anon_rmap() requires CONFIG_MMU]
[willy@infradead.org: folio-compat.c needs rmap.h]
