One of our users cannot delete several buckets with radosgw-admin due to the error like below:

2023-11-28T07:48:32.486+0100 7f323910a840  0 ERROR: cls_bucket_list_unordered error in rgw_rados_operate (bucket list op), r=-27
2023-11-28T07:48:32.486+0100 7f323910a840  0 ERROR: int RGWRados::Bucket::List::list_objects_unordered(const DoutPrefixProvider*, int64_t, std::vector<rgw_bucket_dir_entry>*, std::map<std::__cxx11::basic_string<char>, bool>*, bool*, optional_yield) cls_bucket_list_unordered returned -27 for :CENSOREDBUCKETNAME[abc69c9f-3a61-465b-aa4d-4110bf79d972.896755.1])

So it looks like when the osd's rgw_bucket_list returns RGWBIAdvanceAndRetryError this spacial error code is not handled correctly in the case of unordered list and just bubble up to the upper layer as an ordinary error.

The `radosgw-admin bucket list --allow-unordered` also fails for these buckets:

ERROR: store->list_objects(): 2023-11-29T12:45:44.952+0100 7ff772ff7840  0 ERROR: cls_bucket_list_unordered error in rgw_rados_operate (bucket list op), r=-27
(27) File too large2023-11-29T12:45:44.952+0100 7ff772ff7840  0 ERROR: int RGWRados::Bucket::List::list_objects_unordered(const DoutPrefixProvider*, int64_t, std::vector<rgw_bucket_dir_entry>*, std::map<std::__cxx11::basic_string<char>, bool>*, bool*, optional_yield) cls_bucket_list_unordered returned -27 for :CENSOREDBUCKETNAME[abc69c9f-3a61-465b-aa4d-4110bf79d972.896755.1])

The buckets use versioning and I suppose this is the source of so large number of "not visible" entries that it has to return RGWBIAdvanceAndRetryError.
