[RESEND PATCH v2 16/19] sched/idle: Switch to use hrtimer_setup_on_stack()

[Nam Cao]

hrtimer_setup_on_stack() takes the callback function pointer as argument
and initializes the timer completely.

Replace hrtimer_init_on_stack() and the open coded initialization of
hrtimer::function with the new setup mechanism.

The conversion was done with Coccinelle.
