memcg: don't call memcg_update_all_caches if new cache id fits
memcg_update_all_caches grows arrays of per-memcg caches, so we only need
to call it when memcg_limited_groups_array_size is increased. However,
currently we invoke it each time a new kmem-active memory cgroup is
created. Then it just iterates over all slab_caches and does nothing
(memcg_update_cache_size returns immediately).
This patch fixes this insanity. In the meantime it moves the code dealing
with id allocations to separate functions, memcg_alloc_cache_id and
memcg_free_cache_id.
