libnvdimm: handle locked label storage areas
Per the latest version of the "NVDIMM DSM Interface Example" [1], the label data retrieval routine can report a "locked" status. In this case all regions associated with that DIMM are disabled until the label area is unlocked. Provide generic libnvdimm enabling for NVDIMMs with label data area locking capabilities.
