sr: use skb_get_hash_net() in seg6_make_flowlabel()\nSince commit d58e468b1112 (\"flow_dissector: implements flow dissectorBPF hook\") __skb_flow_dissect() needs a net pointer, either fromskb->dev, skb->sk, or since commit 3cbf4ffba5ee (\"net: plumb networknamespace into __skb_flow_dissect\") a caller provided pointer.\nsyzbot was able to reach seg6_make_flowlabel() with an skb havingneither skb->dev nor skb->sk set: a TIPC UDP bearer sends a discoverymessage through an IPv4 route using seg6 encap, whilenet.ipv6.seg6_flowlabel is set to 1.\nseg6_make_flowlabel() already has a net pointer,
