Filtering reverse relations against invalid lookups crashes.

{{{#!python
from django.db import models

class Author(models.Model):
name = models.CharField(max_length=10)

class Report(models.Model):
name = models.CharField(max_length=10)
creator = models.ForeignKey(Author, models.CASCADE)

>>> Author.objects.filter(report__title="first")
...
File "/django/django/db/models/expressions.py", line 380, in
get_transform
return self.output_field.get_transform(name)
AttributeError: 'ManyToOneRel' object has no attribute 'get_transform'
}}}

In Django 4.1 it raises `django.core.exceptions.FieldError: Related Field
got invalid lookup: title`.
