Hitting an inbound connection error can lead to InvalidStreamIDForPeer errors when acting as a client.

[Lukasa]

The code that handles shutting down on inboundConnectionError tends to hit InvalidStreamIDForPeer. This is because we attempt to send a GOAWAY with lastStreamID set to .maxID, which is technically an invalid stream ID for the peer. We should modify the check here, as it's reasonable to want to set .maxID in this case, even though the server cannot technically emit such a stream ID.
