[PATCH 1/6 v2] sched: Init idle->on_rq in init_idle()

[Sebastian Andrzej Siewior <bigeasy@linutronix.de>]

The init task is state TASK_RUNNING and on_irq should be set to 1. It won't
be set by scheduler because the idle task is never woken up, it is always the
task we fall back to if there is no other task pending.
