Backport gvnic XDP native support for DQ

(drivers/net/ethernet/google/gve/gve_rx_dqo.c)
gve_dma_sync was introduced later but does the same thing as
dma_sync_single_range_for_cpu, so gve_dma_sync was kept.

(drivers/net/ethernet/google/gve/gve_rx_dqo.c)
Conflict resolution done with if (eop && buf_len <= priv->rx_copybreak)
such that the if statement pairs correctly.
