mlx4: mark napi id for gro_skb
Napi id was not marked for gro_skb, this will lead rx busy loop won't work correctly since they stack never try to call low latency receive method because of a zero socket napi id. Fix this by marking napi id for gro_skb. The transaction rate of 1 byte netperf tcp_rr gets about 50% increased (from 20531.68 to 30610.88).
