mm: filter zone device pages returned from folio_walk_start()
Previously dax pages were skipped by the pagewalk code as pud_special() or
vm_normal_page{_pmd}() would be false for DAX pages. Now that dax pages
are refcounted normally that is no longer the case, so the pagewalk code
will start returning them.
Most callers already explicitly filter for DAX or zone device pages so
don't need updating. However some don't, so add checks to those callers.
