mm/folio: replace set_compound_order with folio_set_order

The patch ("mm/folio: Avoid special handling for order value 0 in
folio_set_order") [1] removed the need for special handling of order = 0
in folio_set_order.  Now, folio_set_order and set_compound_order becomes
similar function.  This patch removes the set_compound_order and uses
folio_set_order instead.
