Add SCSI host and device info not elsewhere available to /proc/scsi/cciss/*
Namely, connect cciss device instance with scsi host number, and give scsi
host number, bus, target, lun, devicetype, and 8-byte cciss LUNID for each
tapedrive/medium changer attached to a controller

For instance:

# cat /proc/scsi/cciss/2
cciss0: SCSI host: 2
c2b0t0l0 01 0x0000000000000001
