Subject: memcg: don't initialize kmem-cache destroying work for root caches
struct memcg_cache_params has a union. Different parts of this union are
used for root and non-root caches. A part with destroying work is used
only for non-root caches.
I fixed the same problem in another place v3.9-rc1-16204-gf101a94, but
didn't notice this one.
