We first wait for a request to be submitted to hw and assigned a seqno, before we can wait for the hw to signal completion (otherwise we don't know the hw id we need to wait upon). Whilst waiting for the request to be submitted, we may exceed the user's timeout and need to propagate the error back. v2: Make ETIME into an error from wait_for_execute for consistent exit handling.
