net: ipv6: Fix oif in TCP SYN+ACK route lookup.
net-next commit 9c76a11, ipv6: tcp_ipv6 policy route issue, had
a boolean logic error that caused incorrect behaviour for TCP
SYN+ACK when oif-based rules are in use. Specifically:
1. If a SYN comes in from a global address, and sk_bound_dev_if
is not set, the routing lookup has oif set to the interface
the SYN came in on. Instead, it should have oif unset,
because for global addresses, the incoming interface doesn't
necessarily have any bearing on the interface the SYN+ACK is
sent out on.
2. If a SYN comes in from a link-local address, and
sk_bound_dev_if is set, the routing lookup has oif set to the
interface the SYN came in on. Instead, it should have oif set
to sk_bound_dev_if, because that's what the application
requested.
