mm/hugetlb: use direct assignment instead of folio_change_private()

folio_change_private() should be used along with folio_attach_private() and
folio_detach_private(), where adding and remove ->private content requires
folio refcount change. add_hugetlb_folio() simply sets folio->private to
NULL without refcount manipulation. Change it to direct assignment to avoid
semantic confusion.

It prepares for a future commit that remove PG_private.

No functional change intended.
