sched/eevdf: Fix miscalculation in reweight_entity() when se is not curr
[ Upstream commit afae8002b4fd3560c8f5f1567f3c3202c30a70fa ]
reweight_eevdf() only keeps V unchanged inside itself. When se !=
cfs_rq->curr, it would be dequeued from rb tree first. So that V is
changed and the result is wrong. Pass the original V to reweight_eevdf()
to fix this issue.
