[PATCH V2 09/20] nvdimm/namespace_label: Skip region label during ns label DPA reservation

[Neeraj Kumar]

If Namespace label is present in LSA during nvdimm_probe then DPA
reservation is required. But this reservation is not required by region
label. Therefore if LSA scanning finds any region label, skip it.
