sched: fix stale value in average load per task
Impact: fix load balancer load average calculation accuracy
cpu_avg_load_per_task() returns a stale value when nr_running is 0.
It returns an older stale (caculated when nr_running was non zero) value.
This patch returns and sets rq->avg_load_per_task to zero when nr_running
is 0.
Compile and boot tested on a x86_64 box.
