Subject: cgroup: downgrade error message when we cannot remove a cgroup to debug

cgroup: downgrade error message when we cannot remove a cgroup to debug

Some units set KillMode=none to survive the initrd→rootfs transition. We
cannot remove their cgroups, but that shouldn't really be considered an
issue, so let's downgrade the error message.
