schedcore: Remove duplicated init_task's preempt_notifiers init
init_task's preempt_notifiers is initialized twice:
1) sched_init()
-> INIT_HLIST_HEAD(&init_task.preempt_notifiers)
2) sched_init()
-> init_idle(current,) <--- current task is init_task at this time
-> __sched_fork(,current)
-> INIT_HLIST_HEAD(&p->preempt_notifiers)
I think the first one is unnecessary, so remove it.
