Kanchana P Sridhar 6e1fa555ec mm: zswap: modify zswap_stored_pages to be atomic_long_t ...

For zswap_store() to support large folios, we need to be able to do a
batch update of zswap_stored_pages upon successful store of all pages in
the folio.  For this, we need to add folio_nr_pages(), which returns a
long, to zswap_stored_pages.
