[net-next 3/8] ixgbevf: Make use of NETIF_F_RXCSUM instead of keeping our own flag

From: Alexander Duyck <redacted> The IXGBE_FLAG_RX_CSUM_ENABLED flag is redundant since NETIF_F_RXCSUM is keeping the value we want to already have. As such we can drop the redundant flag and just make use of NETIF_F_RXCSUM.
