Make confd answer disk requests querying by name
Make confd answer disk requests querying by name

As a result of an additional bit of code introduced by patch fa3c0df5,
queries for instance disks sent to the configuration daemon required
additional information about the instance. This information was fetched
through a manual search of the list of instances, rather than the
function capable of searching by name or by uuid.

This made the burnin tool used by our tests fail when inquiring for
information and broke QA, and this patch fixes the problem.
