[NETNS]: The ip6_fib_timer can work with garbage on net namespace stop.
The del_timer() function doesn't guarantee, that the timer callback
is not active by the time it exits.
Thus, the fib6_net_exit() may kfree() all the data, that is required
by the fib6_run_gc(). The race window is tiny, but slab poisoning can
trigger this bug.
Using del_timer_sync() will cure this.
