The _task_util_est() is mainly used to add/remove the task contribution to/from the rq's estimated utilization at task enqueue/dequeue time. In both cases we ensure the UTIL_AVG_UNCHANGED flag is set to keep consistency between enqueue and dequeue time while still being transparent to update_load_avg calls which will eventually reset the flag. Let's move the flag forcing within _task_util_est() itself so that we can simplify calling code by hiding that estimated utilization implementation detail into one of its internal functions. This will affect also the "public" API task_util_est() but we know that the flag will (eventually) impact just on the LSB of the estimated utilization, thus it's certainly acceptable.
