memcg: remove unused mem_cgroup_id() and mem_cgroup_from_id()

Browse source

Now that all callers have been converted to use either:
 - The private ID APIs (mem_cgroup_private_id/mem_cgroup_from_private_id)
   for internal kernel objects that outlive their cgroup
 - The public cgroup ID APIs (mem_cgroup_ino/mem_cgroup_get_from_ino)
   for external interfaces

Remove the unused wrapper functions mem_cgroup_id() and
mem_cgroup_from_id() along with their !CONFIG_MEMCG stubs.
