Martin K. Petersen c446c1f990 [SCSI] scsi_trace: Enhance SCSI command tracing 
Various SCSI trace enhancements:

 - Display data and protection information scatterlist lengths in the
   trace output

 - Add support for VERIFY and WRITE SAME commands and decode the UNMAP
   bit if applicable

 - Add decoding of the PROTECT field for READ/VERIFY/WRITE/WRITE SAME
   commands as well as the EXPECTED INITIAL REFERENCE TAG field for
   their 32-byte variants

 - Decode READ CAPACITY(16), GET LBA STATUS, and UNMAP
