sched/cputime: Simplify task_cputime()
Now since fetch_task_cputime() has no other users than task_cputime(),
its code could be used directly in task_cputime().
Moreover since only 2 task_cputime() calls of 17 use a NULL argument,
we can add dummy variables to those calls and remove NULL checks from
task_cputimes().
Also remove NULL checks from task_cputimes_scaled().
