### What problem does this PR solve?
Fix bvar leak after alter tablet job failed.
How to reproduce:
1、create table
```
CREATE TABLE `test_tbl` (
`uid` int NOT NULL,
`vid` varchar(600) NOT NULL,
`pid` varchar(100) NOT NULL,
`create_day` date NOT NULL,
`create_time` datetime NOT NULL
) ENGINE=OLAP
UNIQUE KEY(`uid`, `vid`, `pid`, `create_day`)
PARTITION BY RANGE(`create_day`)
(PARTITION p20250908 VALUES [('2025-09-08'), ('2025-09-09')),
PARTITION p20250909 VALUES [('2025-09-09'), ('2025-09-10')),
PARTITION p20250910 VALUES [('2025-09-10'), ('2025-09-11')))
DISTRIBUTED BY HASH(`uid`) BUCKETS 32
```
2、insert some value
```
insert into test_tbl values(1, 'a', 'b', '2025-09-08', '2025-09-08
00:00:00');
...
```
3、open be debug point
```
curl -X POST
"http://127.0.0.1:8040/api/debug_point/add/CloudSchemaChangeJob::_convert_historical_rowsets.fail.before.commit_job";
{
"status": "OK",
"msg": "OK"
}
```
4、alter table add rollup
```
create materialized view test_tbl_3 as select uid, vid, pid, create_day
from test_tbl \G;
```
5、show alter table rollup
```
mysql> show alter table rollup\G;

6、Now the bvar fragment_executing_count is add but never reduce, leak
happened.
