Hailo-10H / HailoRT 5.4.0: ConfiguredInferModel::run_async_for_duration() always fails with HAILO_RPC_FAILED (77) — host seems to parse the reply from the header, not the body

On Hailo-10H, run_async_for_duration() fails on every call with status 77, after waiting the full requested duration. From reading the v5.4.0 source, I think the host-side reply parsing reads from the wrong offset. Details, a minimal reproduction and a suggested one-line fix are below.
