4.11-stable review patch. If anyone has any objections, please let me know.

commit 310b4816a5d8082416b4ab83e5a7b3cb92883a4d upstream.
a590b90d472f ("cgroup: fix spurious warnings on cgroup_is_dead() from cgroup_sk_alloc()") converted most cgroup_get() usages to cgroup_get_live() leaving cgroup_sk_alloc() the sole user of cgroup_get(). When !CONFIG_SOCK_CGROUP_DATA, this ends up triggering unused warning for cgroup_get().
Silence the warning by adding __maybe_unused to cgroup_get().
