tx_bufs/tx_count and rx_bufs/rx_count can be hold in another dedicated structure, thus reducing the number of parameters to transceive. This permits to avoid using the stack when calling transceive. Since we saved parameters, we can expose back the struct device pointer, to stay consistent with other device driver APIs.
