MDEV-31003 has introduced second execution for SELECTs that execute under ps-protocol. The following tests in galera suites do not support this mode of execution, disable it: galera.MDEV-27862 galera.galera_log_output_csv galera.galera_query_cache galera.galera_query_cache_sync_wait galera_3nodes_sr.GCF-336 galera_3nodes_sr.galera_sr_isolate_master galera_sr.galera_sr_large_fragment galera_sr.galera_sr_many_fragments Signed-off-by: Julius Goryavsky <julius.goryavsky@mariadb.com>
