Subject: mm: memcontrol: rename memcg_cache_id to memcg_kmem_id

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.
