State-Changed-Why: 
The constant '1' passed in ccb_flags tells CAM that the cdb data area
contains a pointer to the CDB instead of the direct CDB bytes.  This
feature of the ANSI CAM spec is not universally supported by all CAM
SIMs and most likely is not supported well by the XPT.  We need to discuss
whether this feature is worth preserving in CAM and how best to implement
it to reduce the burden on SIM drivers.
