iio:imu:bmi160: Fix too large a buffer.
commit dc7de42d6b50a07b37feeba4c6b5136290fcee81 upstream. The comment implies this device has 3 sensor types, but it only has an accelerometer and a gyroscope (both 3D). As such the buffer does not need to be as long as stated. Note I've separated this from the following patch which fixes the alignment for passing to iio_push_to_buffers_with_timestamp() as they are different issues even if they affect the same line of code.
