l2tp: prevent tunnel creation on netns mismatch
l2tp_tunnel_create is passed a pointer to the network namespace for the tunnel, along with an optional file descriptor for the tunnel which may be passed in from userspace via. netlink. In the case where the file descriptor is defined, ensure that the namespace associated with that socket matches the namespace explicitly passed to l2tp_tunnel_create.
