mm/page_table_check: reinstate address parameter in [__]page_table_check_pte_clear()
This reverts commit aa232204c4 ("mm/page_table_check: remove unused
parameter in [__]page_table_check_pte_clear").
Reinstate previously unused parameters for the purpose of supporting
powerpc platforms, as many do not encode user/kernel ownership of the page
in the pte, but instead in the address of the access.
