Laurent Vivier be2960baae cpu: don't allow negative core id
With pseries machine type a negative core-id is not managed properly:
-1 gives an inaccurate error message ("core -1 already populated"),
-2 crashes QEMU (core dump)

As it seems a negative value is invalid for any architecture,
instead of checking this in spapr_core_pre_plug() I think it's better
to check this in the generic part, core_prop_set_core_id()
