It can't work.
avg.decay_count needs to be set to 0 before enqueue_entity_load_avg(), then
update_entity_load_avg() can't be called, so, runnable_avg_period/sum
are unusable.
Even we has chance to call __update_entity_runnable_avg(),
avg.last_runnable_update needs be set before that, usually, it needs to
be set as 'now', that cause __update_entity_runnable_avg() function
return 0, then update_entity_load_avg() still can not reach to
__update_entity_load_avg_contrib().
If we embed a simple new task load initialization to many functions,
that is too hard for future reader.
