cgroup: mark cgroup_get() with __maybe_unused
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().
