iio: hid-sensor-als: Return 0 for HID_USAGE_SENSOR_TIME_TIMESTAMP

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.
