== Issue

When explicitly setting {{{ form_kwargs = {'empty_permitted':True} }}} or
{{{ form_kwargs = {'empty_permitted':False} }}}, a KeyError occurs when
rendering a template that uses a formset's {{{empty_form}}}.

== Expected Behavior

{{{empty_permitted}}} is ignored for {{{formset.empty_form}}} since
{{{empty_permitted}}} is irrelevant for {{{empty_form}}}, as
{{{empty_form}}} is not meant to be used to pass data and therefore does
not need to be validated.

== Steps to Reproduce

{{{#!python
# views.py
from django.shortcuts import render
from .models import MyModel

def test_view(request):
context = {}
ff = modelformset_factory(MyModel, fields = ['a_field'])
context['formset'] = ff(
queryset = MyModel.objects.none(),
form_kwargs = {'empty_permitted':True} # or form_kwargs =
{'empty_permitted':False}
)
return render(request, 'my_app/my_model_formset.html', context)

# urls.py
from django.urls import path, include
from .views import test_view

urlpatterns = [
path('test', test_view)
]

# my_model_formset.html
{% extends "my_app/base.html" %}

{% block content %}
<form id="my-form" method="post">
{% csrf_token %}
{{ formset }}
<input type="submit" value="Save">
</form>

{{ formset.empty_form }}

{% endblock %}
}}}
