memcg: rename some cache id related variables
memcg_limited_groups_array_size, which defines the size of memcg_caches arrays, sounds rather cumbersome. Also it doesn't point anyhow that it's related to kmem/caches stuff. So let's rename it to memcg_nr_cache_ids. It's concise and points us directly to memcg_cache_id. Also, rename kmem_limited_groups to memcg_cache_ida.
