Prevent calling rte_eth_xstats_get not initialized dev
DPDK API forbids calling rte_eth_xstats_get on a port
which has not been setup up yet.
Citing the DPDK docs (reformated):
"
The functions exported by the application Ethernet API to setup a device
designated by its port identifier must be invoked in the following order:
rte_eth_dev_configure()
rte_eth_tx_queue_setup()
rte_eth_rx_queue_setup()
rte_eth_dev_start()
Then, the network application can invoke, in any order, the functions
exported by the Ethernet API to get the MAC address of a given device,
to get the speed and the status of a device physical link, to
receive/transmit [burst of] packets, and so on.
"
