##### SUMMARY
<!-- Explain the problem/feature briefly -->
In Xenserver/XCP_NG backend, when a chain of snapshots exists, the cleanup
of old snapshot files is not taking place correctly. Old snapshots contnue to
exist, while some in the middle are destroyed and files are deleted as well,
but older ones continue to exist.
##### STEPS TO REPRODUCE
<!--
For bugs, show exactly how to reproduce the problem, using a minimal
test-case. Use Screenshots if accurate.
For new features, show how the feature would be used.

<!-- Paste example playbooks or commands between quotes below -->
~~~
I have not found a sure way to recreate this issue. Here is what I have
though - Setup xcp-ng backend, ver 8.2. Set snapshot.delta.max = 7, setup a
Volume with Daily Snapshot and Keep =3.
Over time, you will start seeing this discrepency

<!-- You can also paste gist.github.com links for larger files -->
##### EXPECTED RESULTS
<!-- What did you expect to happen when running the steps above? -->
~~~
The Keep = 3 should get respected, and besides the required chain of the
last 3 snapshots, all old snapshot files should physically be deleted.
~~~
##### ACTUAL RESULTS
<!-- What actually happened? -->
<!-- Paste verbatim command output between quotes below -->
~~~
old files continue to exist.
Example -
and Physical file view
I have Keep = 3, I expect that the Aug 6 and Aug 7 files will exist,
I also expect that Aug 5 file will exist (keep = 3), but since Aug 5 file is
part of a chain (by looking at file size), all Files from Jul 30 to Aug 5 need
to be kept.
However, Jul 3, 4 and 6 files should not exist. These files also show as
"Ready" in the snapshot_store_ref above.
