nvme: catch -ENODEV from nvme_revalidate_zones again
nvme_revalidate_zones can also return -ENODEV if e.g. zone sizes aren't
constant or not a power of two. In that case we should jump to marking
the gendisk hidden and only support pass through.
Fixes: 602e57c9799c ("nvme: also mark passthrough-only namespaces ready in nvme_update_ns_info")
