[stgt] [PATCH 01/15] tgt: Don't interfere with internal OSD affairs

Short:
* osd.c has no real knowledge of OSD CDB structure. Let back-store
  sort out CDB errors properly.

Long:
* OSD2's CDB size has changed, in fact there are more then one variant.
* The return code and sense structure was wrong for OSD which have more
  specific error descriptions.
* We might support all versions of OSD, dynamically at run time.
* This code was a layering violation and an ugly hack with it's hard coded
  constant numbers.
