Subject: [PATCH v2] mm: swap: Convert mark_page_lazyfree() to folio_mark_lazyfree()

mark_page_lazyfree() and the callers are converted to use folio,
this rename and make it to take in a folio argument instead of
calling page_folio().

v2: use new name, folio_mark_lazyfree() and drop extern suggested by
