You need to pass the id to the form before displaying the form
$mform->set_data($info);
$mform->display();
Also, you should use the single get_record function not the multiple get_records function
$info = $DB->get_record($table, array('id' => $id));
Also, you might want to use the hidden element for the id
$mform->addElement('hidden', 'id');
