* handler::get_auto_increment() was not expecting any errors from the storage engine. That was wrong, errors could happen. * ha_partition::get_auto_increment() was doing index lookups in partition under a mutex. This was redundant (engine transaction isolation was covering that anyway) and harmful (causing deadlocks).
