scsi: mac_scsi: Revise printk(KERN_DEBUG ...) messages

After a bus fault, capture and log the chip registers immediately, if the
NDEBUG_PSEUDO_DMA macro is defined. Remove some printk(KERN_DEBUG ...)
messages that aren't needed any more.  Don't skip the debug message when
bytes == 0. Show all of the byte counters in the debug messages.
