  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().

Can we rename this function to folio_mark_lazyfree() instead so it's more
consistent with other the folio functions. Also I believe we can get rid of
the 'extern' keyword.
