Make the code a little more maintainable by using dc->vmsd to register
the vmstate instead of using vmstate_(un)register calls.

'instance_id' was being set to VMSTATE_INSTANCE_ID_ANY so there is no need
for qdev_set_legacy_instance_id() calls.

spapr_nvdimm_unrealize() was removed since it was only being used to
call vmstate_unregister().
