selinux: Better local/forward check in selinux_ip_postroute()
It turns out that checking to see if skb->sk is NULL is not a very good indicator of a forwarded packet as some locally generated packets also have skb->sk set to NULL. Fix this by not only checking the skb->sk field but also the IP[6]CB(skb)->flags field for the IP[6]SKB_FORWARDED flag. While we are at it, we are calling selinux_parse_skb() much earlier than we really should resulting in potentially wasted cycles parsing packets for information we might no use; so shuffle the code around a bit to fix this.
