page_referenced_one() and page_idle_clear_pte_refs_one() duplicate the code for looking up pte of a (possibly transhuge) page. Move this code to a new helper function, page_check_address_transhuge(), and make the above mentioned functions use it. This is just a cleanup, no functional changes are intended.
