Setup number of Rx & Tx queues to 0 at rte_eth_dev_configure means
take driver's default queue number, so if during a re-configureation
previous queue number will be overwrite, this is not expected when
we configure dcb. The patch fix it by re-confgure device with the
original queue number.
Fixes: 3be82f5cc5e ("ethdev: support PMD-tuned Tx/Rx parameters")

v2:
- directly copy to dev->data->dev_conf is not recommented, now we
reconfigure every queues with same number
