sched_ext: keep running prev when prev->scx.slice != 0
[ Upstream commit 30dd3b13f9de612ef7328ccffcf1a07d0d40ab51 ]
When %SCX_OPS_ENQ_LAST is set and prev->scx.slice != 0,
@prev will be dispacthed into the local DSQ in put_prev_task_scx().
However, pick_task_scx() is executed before put_prev_task_scx(),
so it will not pick @prev.
Set %SCX_RQ_BAL_KEEP in balance_one() to ensure that pick_task_scx()
can pick @prev.
