    bhyve/virtio-scsi: Unlimit max_sectors
    
    The old default of 2 for max_sectors limits performance significantly
    with guest systems where the virtio-scsi driver actually honors this
    value.
    
    As CTL doesn't seem to have any limit of the maximum size of a single
    transfer, set this to INT32_MAX by default.
