[PATCH 5.15 553/779] nvme: catch -ENODEV from nvme_revalidate_zones again

[Greg Kroah-Hartman]

From: Christoph Hellwig <hch@xxxxxx>

[ Upstream commit e06b425bc835ead08b9fd935bf5e47eef473e7a0 ]

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")
