dm: scsi: report correct device number

Before the patch scsi would report the same device number for all SCSI
devices, e.g.

  Device 0: (1:0) Vendor: ATA Prod.: Crucial_CT128M55 Rev: MU01
            Type: Hard Disk
            Capacity: 122104.3 MB = 119.2 GB (250069680 x 512)
  Device 0: (1:0) Vendor: ATA Prod.:  Rev:
            Type: Hard Disk
            Capacity: not available

With the patch the same device number is reported as is used in
scsi_read():

  Device 0: (1:0) Vendor: ATA Prod.: Crucial_CT128M55 Rev: MU01
            Type: Hard Disk
            Capacity: 122104.3 MB = 119.2 GB (250069680 x 512)
  Device 1: (1:0) Vendor: ATA Prod.:  Rev:
            Type: Hard Disk
            Capacity: not available
