[PATCH V4 05/17] nvdimm/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.
