[PATCH v2 1/2] sched/eevdf: Always update V if se->on_rq when reweighting

[Tianchen Ding <dtcccc@linux.alibaba.com>]

reweight_eevdf() needs the latest V to do accurate calculation for new
ve and vd. So update V unconditionally when se is runnable.

Fixes: eab03c23c2a1 ("sched/eevdf: Fix vruntime adjustment on reweight")
