scsi: ufs: Make UPIU trace easier differentiate among CDB, OSF, and TM

Transaction Specific Fields (TSF) in the UPIU package could be CDB
(SCSI/UFS Command Descriptor Block), OSF (Opcode Specific Field), and TM
I/O parameter (Task Management Input/Output Parameter). But, currently, we
take all of these as CDB in the UPIU trace. Thus makes user confuse among
CDB, OSF, and TM message. So fix it with this patch.
