Describe the bug?

This block is a duplicate functionality of the functions __duplicate_m2o_fields and __duplicate_o2m_fields.
And does not use _clone_m2o_or_o2m_fields.
As a result, additional copies of records appear.

I propose a solution - remove this block:

            if (f.many_to_one or f.one_to_many) and instance._state.db != using:
                sub_instance = getattr(instance, f.name, None) or f.get_default()

                if sub_instance is not None:
                    sub_instance = CloneMixin._create_copy_of_instance(
                        sub_instance,
                        force=True,
                        sub_clone=True,
                        using=using,
                    )
                    sub_instance.save(using=using)
                    value = sub_instance.pk

To Reproduce

class Item(Model, CloneMixin):
    pass

class ModelName(Model, CloneMixin):
    items = ForeignKey(Item)

    _clone_m2o_or_o2m_fields = ['item']

ModelName.objects.using('db-id-1').get(pk=1).make_clone(using=DEFAULT_DB_ALIAS)
