public function LegacyWidget::flagErrors

Overrides Drupal\field\Plugin\Type\Widget\WidgetBase::flagErrors().

In D7, hook_field_widget_error() was supposed to call form_error() itself, whereas the new errorElement() method simply returns the element to flag. So we override the flagError() method to be more similar to the previous code in field_default_form_errors().
