mm/rmap: remove do_page_add_anon_rmap()
... and instead convert page_add_anon_rmap() to accept flags.
Passing flags instead of bools is usually nicer either way, and we want to
more often also pass RMAP_EXCLUSIVE in follow up patches when detecting
that an anonymous page is exclusive: for example, when restoring an
anonymous page from a writable migration entry.
This is a preparation for marking an anonymous page inside
page_add_anon_rmap() as exclusive when RMAP_EXCLUSIVE is passed.
