ipip, sit: fix ipv4_{update_pmtu,redirect} calls
[ Upstream commit 2346829e641b804ece9ac9298136b56d9567c278 ]
ipv4_{update_pmtu,redirect} were called with tunnel's ifindex (t->dev is a
tunnel netdevice). It caused wrong route lookup and failure of pmtu update or
redirect. We should use the same ifindex that we use in ip_route_output_* in
*tunnel_xmit code. It is t->parms.link .
