Fixes: #21390

Issue is from CablePath and it having a SET_NULL on the FK relationship which in the handle_deleted_object m2m processing causes a save to the related object, but it has already been handled by Django. CablePath is an internal model and for those (_netbox_private = True) models the m2m processing should probably be skipped.

Skips the m2m handling in handle_deleted_object Django's on_delete handlers already take care of the database integrity. This appears to only effect CablePath as other _netbox_private models - CablePath is the only _netbox_private model that has reverse FK relationships from ChangeLoggingMixin models with on_delete=SET_NULL.
