Generic helper machine_query_hotpluggable_cpus() replaced target specific query_hotpluggable_cpus() callbacks so there is no need in it anymore. However inon NULL callback value is used to detect/report hotpluggable cpus support, therefore it can be removed completely. Replace it with MachineClass.has_hotpluggable_cpus boolean which is sufficient for the task.
