Christoph Hellwig a971ed8002 virtio_blk: remove the broken zone revalidation support
virtblk_revalidate_zones is called unconditionally from
virtblk_config_changed_work from the virtio config_changed callback.

virtblk_revalidate_zones is a bit odd in that it re-clears the zoned
state for host aware or non-zoned devices, which isn't needed unless the
zoned mode changed - but a zone mode change to a host managed model isn't
handled at all, and virtio_blk also doesn't handle any other config
change except for a capacity change is handled (and even if it was
the upper layers above virtio_blk wouldn't handle it very well).

But even the useful case of a size change that would add or remove
zones isn't handled properly as blk_revalidate_disk_zones expects the
device capacity to cover all zones, but the capacity is only updated
after virtblk_revalidate_zones.

As this code appears to be entirely untested and is getting in the way
remove it for now, but it can be readded in a fixed version with
proper test coverage if needed.

Fixes: 95bfec41bd ("virtio-blk: add support for zoned block devices")
Fixes: f1ba4e674f ("virtio-blk: fix to match virtio spec")
