net: Really fix vti6 with oif in dst lookups
6e28b000825d ("net: Fix vti use case with oif in dst lookups for IPv6") is missing the checks on FLOWI_FLAG_SKIP_NH_OIF. Add them. Fixes: 42a7b32b73d6 ("xfrm: Add oif to dst lookups") Cc: Steffen Klassert <steffen.klassert@secunet.com> Signed-off-by: David Ahern <dsa@cumulusnetworks.com> Acked-by: Steffen Klassert <steffen.klassert@secunet.com> Signed-off-by: David S.
