netfilter: nf_dup_ipv6: set again FLOWI_FLAG_KNOWN_NH at flowi6_flags
commit 83170f3beccccd7ceb4f9a0ac0c4dc736afde90c upstream.
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.
Fixes: bbde9fc1824a ("netfilter: factor out packet duplication for IPv4/IPv6")
