e1000: e1000_adapter->polling_netdev is useless
Commit bea3348eef27e6044b6161fd04c3152215f96411 "[NET]: Make NAPI polling independent of struct net_device objects." made NAPI polling to be independent of net_device. So e1000_adapter->polling_netdev is no longer used. Kill it. Signed-off-by: Wang Chen <wangchen@cn.fujitsu.com> Signed-off-by: David S. Miller <davem@davemloft.net>
