s390/topology: call set_sched_topology early
commit 48e9a6c1f54695609b709bf674aac133794ada00 upstream.
The call to topology_init is too late for the set_sched_topology call.
The initial scheduling domain structure has already been established
with default topology array. Use the smp_cpus_done() call to get the
s390 specific topology array registered early enough.
