[SCSI] st: update to use block timeout
Since we're trying to eliminate struct scsi_device timeout, the tape driver has to be updated to use the block queue timeout instead. The tape use of scsi_device timeout looks to be self consistent, so I don't think this necessarily fixes any bug, but it has to be done to allow me to remove the timeout parameter from struct scsi_device.
