s390x/tod-kvm: don't save/restore the TOD in PV guests
Under PV, the guest's TOD clock is under control of the ultravisor and the
hypervisor cannot change it.
With upcoming kernel changes[1], the Linux kernel will reject QEMU's
request to adjust the guest's clock in this case, so don't attempt to set
the clock.
This avoids the following warning message on save/restore of a PV guest:
warning: Unable to set KVM guest TOD clock: Operation not supported
