The s390 specific sched_domain_topology_level should always be used,
not only if the machine provides topology information. Luckily this
odd behaviour, that was by accident introduced with git commit
d05d15da18f5 ("s390/topology: delay initialization of topology cpu
masks") has currently no side effect.
