After invoking transfer_service.finalize, check operation
status by examining DiskStatus.
This is done instead of failing after a predefined timeout
regardless the status.

We can clean this a little bit by doing this outside of the loop.

This should explain the failure:

    "transfer failed: disk %s not found"
 
             pass

This should be a failure now.
 

         # Write the disk ID file.  Only do this on successful completion.

Waiting only for the disk is much nicer.
