net: fix harmonize_features() vs NETIF_F_HIGHDMA
Ashizuka reported a highmem oddity and sent a patch for freescale fec driver. But the problem root cause is that core networking stack must ensure no skb with highmem fragment is ever sent through a device that does not assert NETIF_F_HIGHDMA in its features. We need to call illegal_highdma() from harmonize_features() regardless of CSUM checks. Fixes: ec5f06156423 ("net: Kill link between CSUM and SG features.")
