btr_search_hash_table_validate() does not check if CHECK TABLE is killed

Partial server freeze observed on

origin/bb-10.6-MDEV-31343 f410444a76b5703b803e6e43e3bbf9509b6fddb6 2023-05-25T17:22:33+03:00

Scenario:

1. Start the server + generate some initial data

2. Several connection run a mix of DML and CHECK TABLE.

After some time the processlist shows for all these connections the query

CHECK TABLE <some table> EXTENDED with the state killed.

The reason for the "killed" is most probably max_statement_time = 30.

None of these connections got some response of the server,
