From: Zhao Liu <zhao1.liu@intel.com>
From s390_possible_cpu_arch_ids() in hw/s390x/s390-virtio-ccw.c, the
"core-id" is the index of possible_cpus->cpus[], so it should only be
less than possible_cpus->len, which is equal to ms->smp.max_cpus.
Fix the wrong "core-id" 112, because it isn't less than maxcpus (36) in
-smp, and the valid core ids are 0-35 inclusive.

Changes since v1 RFC:
* Fixed typo. (Nina)
* Polished the description of the reason for fixing the wrong core-id.
