Is the seed used for anything other than the kernel's t10 generation and
verification? It looks like that's all it is for today, and that part is
skipped for userspace metadata, so I'm not sure we need it.
I know it's been used for passthrough commands since nvme started
supporitng it, but I don't see why the driver ever bothered. I think it
wasn't necessary and we've been carrying it forward ever since.
