Description of problem (please be detailed as possible and provide log
snippests):
When deleting snapshot and origin PVC, the restored PVC not activate (remove the k attribue), and there for you can create lots of restores that don't count in thin-pool utilization although their origin has bin deleted.

The restored PVC is the only one left but still in "skip activation" by the k in Vwi-aotz-k 

I can make as much restores PVC and delete their origin snapshot and PVC and still utilization of thin pool will not rise:

Also thin-pool util doesn't change when deleting the origin PVC

Version of all relevant components (if applicable):
4.11.0-113 and checked also older one.

Does this issue impact your ability to continue to work with the product
(please explain in detail what is the user impact)?
Restores are not activated and their utilization not shown.

Is there any workaround available to the best of your knowledge?
No

Rate from 1 - 5 the complexity of the scenario you performed that caused this
bug (1 - very simple, 5 - very complex)?
1

Can this issue reproducible?
Yes

Can this issue reproduce from the UI?
Yes

If this is a regression, please provide more details to justify this:
No

Steps to Reproduce:
1. Install lvmcluster
2. Create a PVC and attach a pod, run IO
3. Create snapshot from the a bove PVC.
4. restore it.
5. Attach a pod to the PVC (to get to bounding mode)
6. Step 4-5 can be repeated to have more PVC with not origin.
7. Delete snapshot, Delete origin PVC. 
8. Check lvs command
repro bash script available at: https://github.com/shyRozen/Toolz/blob/main/repro/snapshot_fs_delete.sh

Actual results:
Many PVC restore that their origin gone and their utilization doesn't count.

Expected results:
The restored PVC should be activated once their snapshot or origin PVC deleted


Additional info:
thinpool-size doesn't change which should be more than half of utilization.
