Oleg Nesterov 229c4ef8ae ftrace: do_each_pid_task() needs rcu lock ...

"ftrace: use struct pid" commit 978f3a45d9
converted ftrace_pid_trace to "struct pid*".

But we can't use do_each_pid_task() without rcu_read_lock() even if
we know the pid itself can't go away (it was pinned in ftrace_pid_write).
The exiting task can detach itself from this pid at any moment.
