I'm going to move the call to memcg_free_cache_id() from the css free
path to css offline. Actually, this is what "[PATCH -mm 08/14] memcg:
release memcg_cache_id on css offline", which is a part of my "Per memcg
slab shrinkers" patch set, does. The css offline path is defined below
css_alloc/free_cache_id, so the forward declaration will be removed
then.

Thanks,
Vladimir
