IIO trigger handlers must call iio_trigger_notify_done() when done. This must be done even when an error occurred. Otherwise the trigger will be seen as busy indefinitely and the trigger handler will never be called again. The itg3200 driver neglects to call iio_trigger_notify_done() when there is an error reading the gyro data. Fix this by making sure that iio_trigger_notify_done() is included in the error exit path.
