netfilter: nf_dup_ipv6: set again FLOWI_FLAG_KNOWN_NH at flowi6_flags
With the commit 48e8aa6e3137 ("ipv6: Set FLOWI_FLAG_KNOWN_NH at flowi6_flags") ip6_pol_route() callers were asked to to set the FLOWI_FLAG_KNOWN_NH properly and xt_TEE was updated accordingly, but with the later refactor in commit bbde9fc1824a ("netfilter: factor out packet duplication for IPv4/IPv6") the flowi6_flags update was lost. This commit re-add it just before the routing decision.
