[PATCH bpf-next v2 2/8] cgroup: Add cgroup_put() in !CONFIG_CGROUPS case

[Yosry Ahmed <yosryahmed-hpIqsD4AKlfQT0dZR+AlfA@public.gmane.org>]

From: Hao Luo <haoluo-hpIqsD4AKlfQT0dZR+AlfA@public.gmane.org>

There is already a cgroup_get_from_id() in the !CONFIG_CGROUPS case,
let's have a matching cgroup_put() in !CONFIG_CGROUPS too.
