planner/core: skip clustered index during admin check table

[tangenta]

What problem does this PR solve?

Problem Summary:

For the tables without any secondary index, admin check table should do nothing.

mysql> create table t(a int, b int, primary key(a, b) clustered);
Query OK, 0 rows affected (0.02 sec)

-- insert into 100000 records

mysql> select count(*) from t;
+----------+
| count(*) |
+----------+
|   100000 |
+----------+
1 row in set (0.11 sec)

mysql> admin check table t;
Query OK, 0 rows affected (0.34 sec)
