libnvdimm/region: Fix label activation vs errors
commit d9cee9f8 upstream. There are a few scenarios where init_active_labels() can return without registering deactivate_labels() to run when the region is disabled. In particular label error injection creates scenarios where a DIMM is disabled, but labels on other DIMMs in the region become activated. Arrange for init_active_labels() to always register deactivate_labels().
