Re: HTTP/2 response completed before its request

CANCEL, because the stream is no longer needed (because you got the response).  Or NO_ERROR, since the request completed successfully.

The stall is half of the problem, but do you cancel the send as well?
If the server has provided a response and closed the stream, there is
no point in continuing to send them data.  Especially if they forget
to send window updates.

RST_STREAM seems appropriate, but what do you think is the right code?
