mm/memory-failure: use folio_mapcount() in hwpoison_user_mappings()
We want to limit the use of page_mapcount() to the places where it is
absolutely necessary. We can only unmap full folios; page_mapped(), which
we check here, is translated to folio_mapped() -- based on
folio_mapcount(). So let's print the folio mapcount instead.
