sched/core: Remove unnecessary initialization init_idle_bootup_task()

init_idle_bootup_task( ) is called in rest_init( ) to switch
the scheduling class of the boot thread to the idle class.

the function only sets:

    idle->sched_class = &idle_sched_class;

which has been set in init_idle() called by sched_init():

    /*
     * The idle tasks have their own, simple scheduling class:
     */
    idle->sched_class = &idle_sched_class;

We've already set the boot thread to idle class in
start_kernel()->sched_init()->init_idle()
so it's unnecessary to set it again in
start_kernel()->rest_init()->init_idle_bootup_task()
