The memcg_cache_id() introduced by commit 2633d7a02823 ("slab/slub:
consider a memcg parameter in kmem_create_cache") is used to index
in the kmem_cache->memcg_params->memcg_caches array. Since
kmem_cache->memcg_params.memcg_caches has been removed by commit
9855609bde03 ("mm: memcg/slab: use a single set of kmem_caches for
all accounted allocations"). So the name does not need to reflect
cache related. Just rename it to memcg_kmem_id. And it can reflect
kmem related.
