[PATCH v3 0/5] Target sense data handling modifications

This patch set modifies the target sense data handling.
First, cleanup transport_send_check_condition_and_sense()
by splitting the sense translation to a separate function.
Second, convert sense reason the switch statement to a table
driven code. Third, Use scsi common helpers to correctly set
the sense buffer. Last, Fix wrong setting of t10-pi errors
(non descriptor format).

Changes from v2:
- Pass sense_reason_t to scsi_translate_sense()
- Split patch 3:
  1) move the helpers to scsi_common.c
  2) use helpers in the target code
  3) always use descriptor-type sense data for PI errors

Changes from v1:
- Added Reviewed-by tags for patches 1,2
- Fixed compilation error after testing patch #3 on scsi/for-next
  branch. Moved scsi_sense_desc_find() to scsi_common as well (dependency)
  and also moved <asm/unaligned.h> include to scsi_common.h

Changes from v0:
- Added Bart's patches and converted my patch to apply over his
- Moved scsi sense helpers to scsi_common
