[PATCH] mm: correct arg in reclaim_pages()/reclaim_clean_pages_from_list()

[Kefeng Wang]

Both of them change the arg from page_list to folio_list when convert
them to use a folio, but not the declaration, let's correct it, also
move the reclaim_pages() from swap.h to internal.h as it only used
in mm.
