s390x/kvm: don't enable key wrapping if msa3 is disabled
As the CPU model now controls msa3, trying to set wrapping keys without
msa3 being around/enable in the kernel will produce misleading errors.
So let's simply not configure key wrapping if msa3 is not enabled and
make compat machines with disabled CPU model work correctly.
