net: ipv6_stub: use ip6_dst_lookup_flow instead of ip6_dst_lookup
commit 6c8991f41546c3c472503dff1ea9daaddf9331c2 upstream.
ipv6_stub uses the ip6_dst_lookup function to allow other modules to
perform IPv6 lookups. However, this function skips the XFRM layer
entirely.
All users of ipv6_stub->ip6_dst_lookup use ip_route_output_flow (via the
ip_route_output_key and ip_route_output helpers) for their IPv4 lookups,
which calls xfrm_lookup_route(). This patch fixes this inconsistent
behavior by switching the stub to ip6_dst_lookup_flow, which also calls
xfrm_lookup_route().
This requires some changes in all the callers, as these two functions
take different arguments and have different return types.
Fixes: 5f81bd2e5d80 ("ipv6: export a stub for IPv6 symbols used by vxlan")

[bwh: Backported to 4.14:
- Drop change in lwt_bpf.c
- Delete now-unused "ret" in mlx5e_route_lookup_ipv6()
- Initialise "out_dev" in mlx5e_create_encap_header_ipv6() to avoid
introducing a spurious "may be used uninitialised" warning
- Adjust filenames, context, indentation]
