Subject: [PATCH] Prevent incorrect tuple size on get_extra_info errors

According to https://docs.python.org/3/library/asyncio-protocol.html#asyncio.BaseTransport.get_extra_info,
get_extra_info fails by returning None. This is an attempt in
normalization of the response in cases of AF_INET, AF_INET6 and
erroneous return values.
