Views Bulk Operation (VBO) modify entity values broken again

Using Views bulk operations modify entity values generates notices when fields that have IEF as the widget are present. This may or may not be a notice only, I couldn't quite tell.

I'm guessing the inline entity form submit rework issue affected this but I'm not sure .. It seems despite the widget being turned off for VBO forms by a previous patch -- that's still working as far as I can tell -- inline_entity_form_field_attach_submit is still called and still looks for the ief_id.

Attach patch might just be hiding the issue.
