Yuyang Du 1269557889 sched/fair: Remove task and group entity load when they are dead 
When task exits or group is destroyed, the entity's load should be
removed from its parent cfs_rq's load. Otherwise, it will take time
for the parent cfs_rq to decay the dead entity's load to 0, which
is not desired.
