[dpdk-stable] [PATCH] net/virtio: fix memory leak

[Pengzhen Liu]

In function eth_virtio_dev_init(), dynamic memory stored
in "eth_dev->data->mac_addrs" variable and it is not freed
when function return,
this is a possible memory leak.

Fixes: 6b9ed026a870 ("net/virtio: eth_dev->data->mac_addrs is not freed")
