mm/zone_device: do not touch device folio after calling ->folio_free()

In the Linux kernel, the following vulnerability has been resolved:

mm/zone_device: do not touch device folio after calling ->folio_free()

The contents of a device folio can immediately change after calling
->folio_free(), as the folio may be reallocated by a driver with a
different order.  Instead of touching the folio again to extract the
pgmap, use the local stack variable when calling percpu_ref_put_many().
