Subject: libnvdimm, namespace: record 'lbasize' for pmem namespaces

Patch-mainline: v4.13-rc1

Git-commit: 2de5148ffb12ff6b4088125f44818771e78e6830

References: FATE#323731

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")
