mm/page_table_check: provide addr parameter to page_table_check_ptes_set()

To provide support for powerpc platforms, provide an addr parameter to the
__page_table_check_ptes_set() and page_table_check_ptes_set() routines. 
This parameter is needed on some powerpc platforms which do not encode
whether a mapping is for user or kernel in the pte.  On such platforms,
this can be inferred from the addr parameter.
