Subject: [RFCv8 PATCH net-next 52/55] net: gve: adjust the prototype of gve_rx(), gve_clean_rx_done() and gve_rx_complete_skb()

The function  gve_rx(), gve_clean_rx_done() and
gve_rx_complete_skb() using netdev_features_t as parameters.

For the prototype of netdev_features_t will be extended to be
larger than 8 bytes, so change the prototype of the function,
change the prototype of input features to 'netdev_features_t *'.
