cgroup: mark cgroup_get() with __maybe_unused
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().
