Eric Dumazet 7115df614b tcp: do not use ipv6 header for ipv4 flow ...

[ Upstream commit 89e4130939 ]

When a dual stack tcp listener accepts an ipv4 flow,
it should not attempt to use an ipv6 header or tcp_v6_iif() helper.

Fixes: 1397ed35f2 ("ipv6: add flowinfo for tcp6 pkt_options for all cases")
Fixes: df3687ffc6 ("ipv6: add the IPV6_FL_F_REFLECT flag to IPV6_FL_A_GET")
Fixes: 1da177e4c3 ("Linux-2.6.12-rc2")
