i386 mm: use pte_update() in ptep_test_and_clear_dirty()
It is not safe to use pte_update_defer() in ptep_test_and_clear_young(): its only user, /proc/<pid>/clear_refs, drops pte lock before flushing TLB. Use the safe though less efficient pte_update() paravirtop in its place. Likewise in ptep_test_and_clear_dirty(), though that has no current use. These are macros (header file dependency stops them from becoming inline functions), so be more liberal with the underscores and parentheses.
