Cleaning up the IPv6 MTU checking in the IPVS xmit code, by using a common helper function __mtu_check_toobig_v6(). The MTU check for tunnel mode can also use this helper as ntohs(old_iph->payload_len) + sizeof(struct ipv6hdr) is qual to skb->len. And the 'mtu' variable have been adjusted before calling helper. Notice, this also fixes a bug, as the the MTU check in ip_vs_dr_xmit_v6() were missing a check for skb_is_gso(). This bug e.g. caused issues for KVM IPVS setups, where different Segmentation Offloading techniques are utilized, between guests, via the virtio driver. This resulted in very bad performance, due to the ICMPv6 "too big" messages didn't affect the sender.
