Notice : Undefined variable: element in entityreference_field_formatter_settings_form() (line 1141 in /sites/all/modules/entityreference/entityreference.module). [#2495405]

When Entity Reference is interacting with different modules, can produce the following error:

Notice : Undefined variable: element in entityreference_field_formatter_settings_form() (line 1141 in /sites/all/modules/entityreference/entityreference.module).

I found it is given because $element is display type is none of the expected ones. I have added a simple check to avoid returning $element if not set.

This seems to be triggered when selecting Entity ID as the display type. Currently noticing this while I try and Formatter Field working with Paragraphs - there's no initialisation for $element taking place in this function.

Here's a really tiny patch that should address the issue.

This is very easy to run into while using the Entity Embed module.

The one-line patch in #2 applies cleanly to Entity Reference 7.x-1.x and ensures that $element is always defined. This is the same approach taken by the example implementation of hook_field_formatter_settings_form() in field_ui.api.php.
