Hao Lee 859e3e45be sched/psi: Fix possible missing or delayed pending event ...

[ Upstream commit e38f89af6a ]

When a pending event exists and growth is less than the threshold, the
current logic is to skip this trigger without generating event. However,
from e6df4ead85 ("psi: fix possible trigger missing in the window"),
our purpose is to generate event as long as pending event exists and the
rate meets the limit, no matter what growth is.
This patch handles this case properly.

Fixes: e6df4ead85 ("psi: fix possible trigger missing in the window")
