Hello Pierre,

The S390 CPU topology accepts the smp.threads argument while
in reality it does not effectively allow multthreading.

Let's keep this behavior for machines older than 7.3 and
refuse to use threads in newer machines until multithreading
is really proposed to the guest by the machine.

This change is unrelated to the rest of the series and we could merge it
for 7.2. We still have time for it.

OK, then I send it on its own

Regards,
Pierre
