Chengming Zhou c530a3c716 sched/psi: Fix periodic aggregation shut off ...

We don't want to wake periodic aggregation work back up if the
task change is the aggregation worker itself going to sleep, or
we'll ping-pong forever.

Previously, we would use psi_task_change() in psi_dequeue() when
task going to sleep, so this check was put in psi_task_change().

But commit 4117cebf1a ("psi: Optimize task switch inside shared cgroups")
defer task sleep handling to psi_task_switch(), won't go through
psi_task_change() anymore.

So this patch move this check to psi_task_switch().

Fixes: 4117cebf1a ("psi: Optimize task switch inside shared cgroups")
