Commit f979b13c3cc5 "libnvdimm, label: honor the lba size specified in
v1.2 labels") neglected to update the 'lbasize' in the label when the
namespace sector_size attribute was written. We need this value in the
label for inter-OS / pre-OS compatibility.
Fixes: f979b13c3cc5 ("libnvdimm, label: honor the lba size specified in v1.2 labels")
