Bug description: If a hostname which has no corresponding IP
address associated is given to the setup-ds-admin.pl or
setup-ds.pl (e.g., bogus.bogus.bogus.com), then DSUtil.pm
complains with "Can't call method "getText" on an undefined
value".

Fix description: There were 2 missing checks in perl subroutine
checkHostname in DSUtil.pm whether the dialog resource is given
or not.
