spapr_drc: fix realize and unrealize
If object_property_add_alias() returns an error in realize(), we should
propagate it to the caller and certainly not unref the DRC.
Same thing goes for unrealize(). Since object_property_del() is the last
call, we can even get rid of the intermediate Error *.
And finally, unrealize() should undo all registrations performed by
realize().
