mm/damon/vaddr: rename 'damon_young_walk_private->page_sz' to 'folio_sz'
Patch series "mm/damon/{v,p}addr: misc fixups for folio usage". DAMON's monitoring operations set for the virtual and the physical address spaces use folio now, but some code is not reflecting the fact. Further cleanup the code for folio usage. This patch (of 6): DAMON's virtual address space monitoring operations set is using folio now. Rename 'damon_pa_access_chk_result->page_sz' to reflect the fact.
