nvme: add I/O characteristics fields
Several new fields have been introduced in version 1.4 of the NVMe spec at offsets that were defined as reserved in version 1.3d of the NVMe spec. Update the definition of the nvme_id_ns data structure such that it is in sync with version 1.4 of the NVMe spec. This change preserves backwards compatibility.
