[PATCH v1] ether: fix overwriting driver-specific stats

After doing a driver callout to fill in the driver specific
parts of struct rte_eth_stats, rte_eth_stats_get() overwrites
the rx_nombuf member regardless of whether the driver itself
has assigned a value. Any driver-assigned value should take
priority.

Fixes: af75078fece3 ("first public release")
