../hw/scsi/vhost-scsi.c:173:12: error: ‘ret’ may be used uninitialized [-Werror=maybe-uninitialized]

It can be reached when num_queues=0. It probably doesn't make much sense
to instantiate a vhost-scsi with 0 IO queues though. For now, make
vhost_scsi_set_workers() return success/0 anyway, when no workers have
been setup.
