[dpdk-dev] [PATCH v2 1/2] ethdev: stop overriding rx_nombuf by rte_eth_stats_get

[David Harton]

rte_eth_stats_get() unconditonally would set rx_nombuf
even if the device was setting the value.  A check has
been added in rte_eth_stats_get() to leave the device
value in-tact when non-zero.

v2: Fixed braces complaint required by other coding standards.
