We've introduced extra need of compat layer for ip_tunnel_prl{}
for PRL (Potential Router List) management. Though compat_ioctl
is still missing in ipv4/ipv6, let's make the interface more
straight-forward and eliminate extra need for nasty compat layer
anyway since the interface is new for 2.6.26.
