mm/rmap: drop "compound" parameter from page_add_new_anon_rmap()
New anonymous pages are always mapped natively: only THP/khugepaged code
maps a new compound anonymous page and passes "true". Otherwise, we're
just dealing with simple, non-compound pages.
Let's give the interface clearer semantics and document these. Remove the
PageTransCompound() sanity check from page_add_new_anon_rmap().
