Description

ozone fs -ls throws an error for listing a deleted snapshot which is not garbage collected and deleted completely.

Steps to reproduce:

Create two snapshots with some keys in it and list them

sh-4.2$ ozone fs -ls -R ofs://om/vol1/bucket1/.snapshot| grep -i key
-rw-rw-rw-   1 hadoop hadoop       4068 2024-01-04 00:38 ofs://om/vol1/bucket1/.snapshot/snap1/key1
-rw-rw-rw-   1 hadoop hadoop       4068 2024-01-04 00:38 ofs://om/vol1/bucket1/.snapshot/snap2/key1
-rw-rw-rw-   1 hadoop hadoop       4068 2024-01-04 00:39 ofs://om/vol1/bucket1/.snapshot/snap2/key2

Now delete one snapshot and list again before snapshot deleting service does the garbage collection:

sh-4.2$ ozone fs -ls -R ofs://om/vol1/bucket1/.snapshot| grep -i key
-rw-rw-rw-   1 hadoop hadoop       4068 2024-01-04 00:38 ofs://om/vol1/bucket1/.snapshot/snap1/key1
ls: Unable to load snapshot. Snapshot with table key '/vol1/bucket1/snap2' is no longer active

It returns error message instead of simply ignoring the deleted snapshot.
