mm/damon/paddr: increment pa_stat damon address range by folio size

This is to avoid going through all the pages in a folio.  For folio_size >
PAGE_SIZE, damon_get_folio will return NULL for tail pages, so the for
loop in those instances will be a nop.  Have a more efficient loop by just
incrementing the address by folio_size.
