slab: fix to calm down kmemleak warning
After using struct page as slab management, we should not call kmemleak_scan_area(), since struct page isn't the tracking object of kmemleak. Without this patch and if CONFIG_DEBUG_KMEMLEAK is enabled, so many kmemleak warnings are printed. Signed-off-by: Joonsoo Kim <iamjoonsoo.kim@lge.com> Signed-off-by: Pekka Enberg <penberg@iki.fi>
