Correctly parse ECS with a source prefix-length value of 0

It means there is no address there, but the family and source
prefix-length values are still relevant. rfc7871 explicitly says
that the family SHOULD be set to the transport over which the query
is sent if source prefix-length is 0.
It also states that a source prefix-length means the client is
asking that no ECS value be sent.
