pinned is still false after ctr label image io.cri-containerd.pinned=pinned

[yuqitao]

Description

I want pin an image which I have imported, so I use ctr -n k8s.io images label imageName io.cri-containerd.pinned=pinned.
But crictl inspecti imageName still return pinned=false.

CRIService get ImageUpdate event，the image in store does not been updated because these logic：

containerd/pkg/cri/store/image/image.go

Line 132 in edbd387

if oldID == img.ID {

Steps to reproduce the issue

1. ctr -n k8s.io images label docker.io/library/redis:2.8.23 io.cri-containerd.pinned=pinned
2. crictl inspecti docker.io/library/redis:2.8.23

Describe the results you received and expected

crictl inspecti imageName still return pinned=true

What version of containerd are you using?

v1.7.8

I see: #8867; but it seems like this pr does not work.

@Iceber PTAL

#8867 only fixes the pinned issue on pull, but it really doesn't fix the updating of the label.
