I fear that that might get misused and we probably should consider some
trivial range checking and each qemu cpu model would have a valid range
or so.

Or we should better do that in kvm_set_msr_common directly... although
if we do it here, it would require kvm knowing about all those different
microcode revisions and qemu cpu models sounds better...
