In _scsih_probe, delay the call to scsi_add_host until the host has been fully set up. Otherwise, the default .can_queue value of 1 causes scsi-mq to set the block layer request queue size to its minimum size, resulting in awful performance. In _scsih_probe error handling, call mpt3sas_base_detach rather than scsi_remove_host to properly clean up in reverse order. In _scsih_remove, call scsi_remove_host earlier to clean up in reverse order.
