change content of HeaderExchangeChannel#request(java.lang.Object, int) from
DefaultFuture future = DefaultFuture.newFuture(channel, req, timeout); to DefaultFuture future = DefaultFuture.newFuture(this, req, timeout); will be a better way.

Just check the code, hasn't verify it.

Not sure if it works or not, @carryxyh, you may consider to come up a better approach with another pull request.
