mm: convert page_add_anon_rmap() to use a folio internally

Browse source

The API for page_add_anon_rmap() needs to be page-based, because we can
add mappings of individual pages.  But inside the function, we want to
only call compound_head() once and then use the folio APIs instead of the
page APIs that each call compound_head().
