[PATCH] Fix blank network device descriptions in the loader. (#501757)

[Bill Nottingham <notting redhat com>]

This appears to be the source of the problem, and fixes the issue
in brief testing. It is completely baffling to me why this would only
manifest now; it's not like this code has changed since it was
added.
