The routine that applies debug flags to the kmem_cache slabs
inadvertantly prevents non-debug flags from being applied to
those same objects. That is, if slub_debug=<flag>,<slab> is
specified, non-debugged slabs will end up having flags of zero,
and the slabs will be unusable. Fix this by returning the input
flags for non-matching slabs as was done previously.
