hrtimer: Mark the hrtimer_sleeper structure's ->task field __private

Browse Source 
The hrtimer_sleeper structure's ->task field is now used only by the
hrtimer_sleeper_task_get() and hrtimer_sleeper_task_set() functions,
and there is no reason for it to be directly accessed anywhere else.

Therefore, mark this field __private and use ACCESS_PRIVATE() in
hrtimer_sleeper_task_get() and hrtimer_sleeper_task_set().
