virsh-completer: remove excessive labels
Now that we have a shared cleanup section everywhere, delete all the 'error' labels which all contain just 'goto cleanup' anyway. Also remove all the 'cleanup' labels that only 'return ret' - we can simply return NULL instead of jumping to that label. Signed-off-by: Ján Tomko <jtomko@redhat.com>
