[SCSI] sd: make printing use a common prefix
Make SCSI disk printing more consistent:
- Define sd_printk(), sd_print_sense_hdr() and sd_print_result()
- Move relevant header bits into sd.h
- Remove all the legacy disk_name passing and use scsi_disk pointers
where possible
- Switch printk() lines to the new sd_ functions so that output is
consistent
