sched: print sched_cpu_load tracepoint for all CPUs
When select_best_cpu() is called because a task is on a suboptimal
CPU, certain CPUs are skipped because moving the task there would
not make things any better. For the purposes of debugging though it
is useful to always see the state of all CPUs.
