[ Upstream commit 9f6c63285737b141ca25a619add80a96111b8b96 ]
Previously, aborting work could return early after engine reset or resume failure, skipping the necessary runtime_put cleanup leaving the device with incorrect reference count breaking runtime power management state.
Replace early returns with goto statements to ensure runtime_put is always executed.
