Fix pylint invalid-sequence-index false positive for internal_ports (2)

Pylint 3.3.x cannot infer that iterating over
``self.internal_ports`` (``list[dict[str]]``) yields ``dict``
items, so it wrongly flags ``p['id']`` as an invalid sequence index.

Silence the two remaining false positives in dvr_local_router.py
with inline ``# pylint: disable`` comments.
