Whilst this is the minimal fix (and so the right one!) it would be good to change this as a follow up to just use direct returns as then this sort of bug won't get reintroduced and the code will be a bit simpler.

When als_capture_sample() is called with usage ID HID_USAGE_SENSOR_TIME_TIMESTAMP, return 0. The HID sensor core ignores the return value for capture_sample() callback, so return value doesn't make difference. But correct the return value to return success instead of -EINVAL.
