IPV6_FRAG_EXT item is missed for RSS expansion which causes flows like
[1] are wrongly expanded.
Different from other items, IPV6_FRAG_EXT hasn't next field because HW
only support to do hash of UDP/TCP for non-fragment.
This MLX5_EXPANSION_IPV6_FRAG_EXT node in RSS expansion graph only helps
RSS expansion function to locate right node in graph from which start
to expand.
Fixes: 0e5a0d8f7556 ("net/mlx5: support match on IPv6 fragment extension")

flow create 0 ingress pattern eth / ipv6 / udp dst is 250 / vxlan-gpe /
ipv6 / ipv6_frag_ext / end actions rss level 2 types ip end / end
