mm/hugetlb: convert putback_active_hugepage to take in a folio

Convert putback_active_hugepage() to folio_putback_active_hugetlb(), this
removes one user of the Huge Page macros which take in a page.  The
callers in migrate.c are also cleaned up by being able to directly use the
src and dst folio variables.
