ANDROID: sched/fair: call set_next_entity() on the replaced next task

Browse Source 
android_rvh_replace_next_task_fair hook allows vendor modules to
override the next task selected by CFS. However the current code is
not calling set_next_entity() on the hierarchy of the replaced task
in the case where the previous task is CFS. Fix this issue.
