mm: remove remaining uses of PFN_DEV
PFN_DEV was used by callers of dax_direct_access() to figure out if the
returned PFN is associated with a page using pfn_t_has_page() or not.
However all DAX PFNs now require an assoicated ZONE_DEVICE page so can
assume a page exists.
Other users of PFN_DEV were setting it before calling vmf_insert_mixed().
This is unnecessary as it is no longer checked, instead relying on
pfn_valid() to determine if there is an associated page or not.
