David Hildenbrand 5f8856cdae xtensa/mm: convert check_tlb_entry() to sanity check folios
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.
