nvme: add preferred I/O size fields to struct nvme_id_ns_nvm
A subsequent change will use the NPDGL and NPDAL fields of the NVM
Command Set Specific Identify Namespace structure, so add them (and the
handful of intervening fields) to struct nvme_id_ns_nvm. Add an
assertion that the size is still 4 KB.
