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")
