am79c961a: Use net_device_stats from struct net_device
struct net_device has its own struct net_device_stats member, so we can use this one instead of a private copy in the dev_priv struct. Cc: Kulikov Vasiliy <segooon@gmail.com> Signed-off-by: Tobias Klauser <tklauser@distanz.ch> Signed-off-by: David S. Miller <davem@davemloft.net>
