QUIC: ignore server address while looking up a connection.
The server connection check was copied from the common UDP code in c2f5d79cde64.
In QUIC it does not make much sense though. Technically client is not allowed
to migrate to a different server address. However, migrating withing a single
wildcard listening does not seem to affect anything.
