- generalize sense data logic to cope with both fixed and
     descriptor format
   - use KERN_INFO on most printk()s to limit console noise
   - retire mid-level usage of sense_class(), sense_error() and
     sense_valid() macros which are SCSI-1 remnants. Now only
     cpqfcTSinit.c seems to use them
