drivers/net/ethernet/mellanox/mlx5/core/en_ethtool.c: fix build with gcc-4.4.4

drivers/net/ethernet/mellanox/mlx5/core/en_ethtool.c: In function 'mlx5e_set_rxfh':
drivers/net/ethernet/mellanox/mlx5/core/en_ethtool.c:1067: error: unknown field 'rss' specified in initializer

drivers/net/ethernet/mellanox/mlx5/core/en_ethtool.c:1067: warning: (near initialization for 'rrp.<anonymous>')
drivers/net/ethernet/mellanox/mlx5/core/en_ethtool.c:1068: error: unknown field 'rss' specified in initializer

gcc-4.4.4 has issues with anonymous union initializers.  Work around this.
