Also fixes MDEV-24467 Memory not freed after failed INSERT DELAYED Description: In case of an error (e.g. data truncation) during mysql_insert() handling an INSERT DELAYED, the data type specific data in fields (e.g. Field_blob::value) is not taken over by the delayed writer thread. All fields in table_list->table are freed by free_root() immediately after mysql_insert(). To avoid a memory leak, we need to free the specific data before exiting mysql_insert() on error.
