The overall approach looks good.

I wonder if bdrv_get_zoned_info() is really needed since zone_model is
part of BlockLimits and is already fetched via bdrv_refresh_limits().
Was it introduced because the block limits haven't been or cannot be
fetched when zone_model is queried the first time?  It would be nice to
get rid of bdrv_get_zoned_info() if possible.
