* Fixes#8405 - onAllDataRead() is called twice under h2 if the stream times out
Per Servlet semantic, HTTP/2 stream timeout should be ignored.
The code was trying to fail the read via `_contentDemander.onTimeout()`, but
then it was still calling `onContentProducible()`, which was returning `true`
because the state of the read was IDLE (all the request content was read) and
the request was suspended.
Now the code checks if the read was really failed; if it is not, then
`onContentProducible()` is not called and so the idle timeout is ignored.
