Oleg Nesterov 2b5fe6de58 thread_group_cputime: move a couple of callsites outside of ->siglock ...

Impact: relax the locking of cpu-time accounting calls

->siglock buys nothing for thread_group_cputime() in do_sys_times() and
wait_task_zombie() (which btw takes the unrelated parent's ->siglock).

Actually I think do_sys_times() doesn't need ->siglock at all.
