[PATCH] Avoid tracebacks when filling in static network config fields (#474275)

[David Cantrell <dcantrell redhat com>]

If the user changes to static network configuration, we may or may not
have values already that we can populate the fields with.  If we do,
take them.  Otherwise, leave the field blank and keep going.
