Dan Williams c2351e5faa libnvdimm/region: Fix label activation vs errors
commit d9cee9f85b 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().
