Use devm_hid_hw_start_and_open helper to ensure that hid resources are consistent with the device life cycle, and release hid resources before device is released. At the same time, it can avoid the goto-release encoding, drop the fail_and_close and fail_and_stop lables, and directly return the error code when an error occurs.
