This patch fixes creation of new kmem-caches after enabling sanity_checks
for existing mergeable kmem-caches in runtime: before that patch creation
fails because unique name in sysfs already taken by existing kmem-cache.
Unlike to other debug options this doesn't change object layout and could
be enabled and disabled at any time.
