[PATCH v5 05/26] nvme: populate the mandatory subnqn and ver fields

[Klaus Jensen <k.jensen@samsung.com>]

Required for compliance with NVMe revision 1.2.1 or later. See NVM
Express 1.2.1, Section 5.11 ("Identify command"), Figure 90 and Section
7.9 ("NVMe Qualified Names").

This also bumps the supported version to 1.2.1.
