sched: Revert 738d2be, simplify set_task_cpu()

Effectively reverts 738d2be4301007f054541c5c4bf7fb6a361c9b3a.

As demonstrated by Eric, we really need to call __set_task_cpu()
early in the fork() path to properly initialize the various task
state -- specifically the cgroup state through set_task_rq().

[ we could probably fix this by explicitly calling
  __set_task_cpu() from   sched_fork(), but lets try that for the
  next cycle and simply revert to the old behaviour for now. ]
