spapr_init_cpus() currently creates spapr-cpu-core objects via
object_new() and setting their realized property to true. This leaves
their reference count at two, because object_new() adds an initial
reference and the realization attaches them to a default parent object
which also increments the reference count.
This causes a problem if one of these cores is hot unplugged: no
delete event is generated for it because it's reference count doesn't
reach zero when it is detached from it's parent.
Correct this by adding a call to object_unref() in spapr_init_cpus().
