net: ps3_gelic_net: Use napi_alloc_skb() and napi_gro_receive()
Use the napi functions napi_alloc_skb() and napi_gro_receive() instead
of netdev_alloc_skb() and netif_receive_skb() for more efficient packet
receiving. The switch to napi aware functions increases the RX
throughput, reduces the occurrence of retransmissions and improves the
resilience against SKB allocation failures.
