Subject: [PATCH] Fix hashCode() in Http2StreamChannelId

Motivation:
In `Http2StreamChannelId` a `hashCode()` is not consistent with `equals()`.

Modifications:
Make a `Http2StreamChannelId.hashCode()` consistent with `equals()`.

Result:
Faster hash map's operations where the Http2StreamChannelId as keys.
