Matthew Wilcox (Oracle) 92abee9c42 mm: support page_mapcount() on page_has_type() pages ...

commit fd1a745ce03e37945674c14833870a9af0882e2d upstream.

Return 0 for pages which can't be mapped.  This matches how page_mapped()
works.  It is more convenient for users to not have to filter out these
pages.
