[SCSI] constants.c: cleanup, verbose result printing

From: Martin K. Petersen

Clean up constants.c and make result printing more user friendly:

- Refactor the command and sense functions so that the actual
formatting can be called from the various helper functions with the
correct prefix.

- Replace scsi_print_hostbyte() and scsi_print_driverbyte() with
scsi_print_result() which is verbose when CONFIG_SCSI_CONSTANTS is
on.
