[NETNS]: fix net released by rcu callback
When a network namespace reference is held by a network subsystem,
and when this reference is decremented in a rcu update callback, we
must ensure that there is no more outstanding rcu update before
trying to free the network namespace.
In the normal case, the rcu_barrier is called when the network namespace
is exiting in the cleanup_net function.
But when a network namespace creation fails, and the subsystems are
undone (like the cleanup), the rcu_barrier is missing.
This patch adds the missing rcu_barrier.
