I think we should also check if "max" is a supported model
(qemuCaps->tcgCPUModels is already populated at this point) and only use
"qemu" on s390 if "max" is not supported. And please, report the issue
to QEMU developers since one of the reasons behind "max" is its
universal availability on everywhere CPU model expansion is supported.
