    MDEV-15472: Assertion `!is_set() || (m_status == DA_OK_BULK && is_bulk_op())' failure

    MariaDB differs from the upstream for "DDL-like" command. For these,

    it sets binlog_format=STATEMENT for the duration of the statement.

    This doesn't play well with MyRocks, which tries to prevent DML

    commands with binlog_format!=ROW.

    Also, if Locked_tables_list::reopen_tables() returned an error, then

    close_cached_tables should propagate the error condition and not silently

    consume it (it's difficult to have test coverage for this because this

    error condition is rare)
