Eric Dumazet 1e98a0f08a flow_dissector: fix ipv6 dst, hop-by-hop and routing ext hdrs
__skb_header_pointer() returns a pointer that must be checked.

Fixes infinite loop reported by Alexei, and add __must_check to
catch these errors earlier.

Fixes: 6a74fcf426f5 ("flow_dissector: add support for dst, hop-by-hop and routing ext hdrs")
