Host1x doesn't have information about jobs inter-dependency, that is something that will become available once host1x will get a proper jobs scheduler implementation. Currently a hang job causes other unrelated jobs to be canceled, that is a relic from downstream driver which is irrelevant to upstream. Let's cancel only the hanging job and not to touch other jobs in queue.
