In its current state my patch will skip a vscsidev in state 5+6 when
collecting the various vscsi-devs/dev-N on a vscsictrl.

However right now its not entirely clear to me if that is correct.
During scsi-attach the vscsidevs get added to JSON, but scsi-detach will
not remove them from JSON. Thats just like ordinary devices. At what
point must the JSON be synced with xenstore? I think at 'xl save/ migrate'.

I think I have to revisit this once I sent out the current state of my
patches, which will not be before Friday this week.
