ieee1394: sbp2: more concise names for types and variables
"struct scsi_id_instance_data" represents a logical unit. Rename it to "struct sbp2_lu", and "scsi_id" to "lu". Rename some other variables too. Wrap almost all lines after at most 80 columns. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
