We want to limit the use of page_mapcount() to the places where it is absolutely necessary. So let's convert check_tlb_entry() to perform sanity checks on folios instead of pages. This essentially already happened: page_count() is mapped to folio_ref_count(), and page_mapped() to folio_mapped() internally. However, we would have printed the page_mapount(), which does not really match what page_mapped() would have checked. Let's simply print the folio mapcount to avoid using page_mapcount(). For small folios there is no change.
