exit_task_namespaces() has replaced the former exit_namespace(). It
invalidates task->nsproxy and associated namespaces. This is an issue
for the (futur) pid namespace which is required to be valid in
exit_notify().

This patch moves exit_task_namespaces() after exit_notify() to keep
nsproxy valid.
