CPU hotplug and coldplug aren't supported prior to pseries-2.7. Further, earlier machine types don't use CPU core objects at all. These mean that query-hotpluggable-cpus and coldplug on older pseries machines will crash QEMU. It also means that hotpluggable_cpus flag in query-machines will be incorrectly set to true for pseries < 2.7, since it is based on the presence of the query_hotpluggable_cpus hook. - Don't assign the query_hotpluggable_cpus hook for pseries < 2.7 - query_hotpluggable_cpus should therefore never be called on pseries < 2.7, so add an assert - spapr_core_pre_plug() should fail hot/cold plug attempts for pseries < 2.7, since core objects are never used there - spapr_core_plug() should therefore never be called for pseries < 2.7, so add an assert.
