sched/fair: Simplify post_init_entity_util_avg() by calling it with a task_struct pointer argument
Since commit:
d03266910a53 ("sched/fair: Fix task group initialization")
the utilization of a sched entity representing a task group is no longer
initialized to any other value than 0. So post_init_entity_util_avg() is
only used for tasks, not for sched_entities.
Make this clear by calling it with a task_struct pointer argument which
also eliminates the entity_is_task(se) if condition in the fork path and
get rid of the stale comment in remove_entity_load_avg() accordingly.
