[et-mgmt-tools] [PATCH 2 of 4] Fix typo and better error message

[David Lutterkort]

When generating error message about a bad reference from a drive to a disk,
use disk_id attribute for the drive and make it clearer that we are talking
about a problem in the XML, not that a file is actually missing.
