TiDB crashes when preprocessing `UPDATE` statement.

## Bug Report

## Bug Report

### 1. Minimal reproduce step (Required)

1. Compile the TiDB using the source repository: [link](https://github.com/pingcap/tidb)
2. Check out with the latest master version: 0c3bbc127c, also tested with released version: v7.4.0-alpha (d43359a55705).
3. Compile the TiDB server using go1.21.0. Use `make` in the repo root directory.
4. Launch TiDB server using command:

```bash
./tidb-server -P 8000 -socket /tmp/mysql_0.sql -path $(pwd)/db_data
```

5. Connect to the server using mysql client:

```bash
mysql -h 127.0.0.1 -P 8000 -u root --socket /tmp/mysql_0.sql
```

6. Input the PoC Query to trigger the crash of the server.

```sql
create databse test;
use test;
WITH RECURSIVE ta1 AS (SELECT 'anyText' ) UPDATE ta0 AS OF TIMESTAMP ? IN (SELECT TRUE ) SET ta0.random_iden = DEFAULT;
```

### 2. What did you expect to see? (Required)

The TiDB Server should continue running.

### 3. What did you see instead (Required)

The TiDB-server crashes and then returns error:

```
ERROR 1105 (HY000): runtime error: invalid memory address or nil pointer dereference
```

Here is a more detailed stack trace from the v7.4.0-alpha (d43359a55705):
