sched: update comment for move_task_off_dead_cpu
Impact: cleanup
This commit:
commit f7b4cddcc5aca03e80e357360c9424dfba5056c2

do CPU_DEAD migrating under read_lock(tasklist) instead of write_lock_irq(ta
Currently move_task_off_dead_cpu() is called under
write_lock_irq(tasklist). This means it can't use task_lock() which is
needed to improve migrating to take task's ->cpuset into account.
Change the code to call move_task_off_dead_cpu() with irqs enabled, and
change migrate_live_tasks() to use read_lock(tasklist).
...forgot to update the comment in front of move_task_off_dead_cpu.
