Undefined index: #entityform in ajax_form_entity_entity_view_alter()

Hi,

When submitting an entity form, I get the following error messages:

Notice: Undefined index: #entityform in ajax_form_entity_entity_view_alter() (line 439 of ...\sites\all\modules\contrib\ajax_form_entity\ajax_form_entity.module).
    Notice: Undefined index: #entityform in ajax_form_entity_entity_view_alter() (line 440 of ...\sites\all\modules\contrib\ajax_form_entity\ajax_form_entity.module).
    Notice: Trying to get property of non-object in ajax_form_entity_entity_view_alter() (line 440 of
...\sites\all\modules\contrib\ajax_form_entity\ajax_form_entity.module).

The attached patch hides these notices, but I didn't test if it works afterwards (I don't use edit/delete links so I'm not sure if the code still works).
