Eric Dumazet 5b73845cd7 l2tp: fix a race in l2tp_ip_sendmsg() ...

[ Upstream commit 4399a4df98 ]

Commit 081b1b1bb2 (l2tp: fix l2tp_ip_sendmsg() route handling) added
a race, in case IP route cache is disabled.

In this case, we should not do the dst_release(&rt->dst), since it'll
free the dst immediately, instead of waiting a RCU grace period.
