Per definition, rte_eth_rx_burst/rte_eth_tx_burst/rte_eth_rx_queue_count returns the packet number.
When RTE_LIBRTE_ETHDEV_DEBUG turns on, retval of FUNC_PTR_OR_ERR_RTE was set to -ENOTSUP.
It makes confusing.
The patch always return 0 no matter no packet or there's error.
Meanwhile set errno in such kind of checking.
