[PATCH v3 03/12] sched: fix avg_load computation

[Vincent Guittot]

The computation of avg_load and avg_load_per_task should only takes into
account the number of cfs tasks. The non cfs task are already taken into
account by decreasing the cpu's capacity (cpu_power) and they will be tracked
in the CPU's utilization (group_utilization) of the next patches
