4.5-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Dan Williams <dan.j.williams@intel.com>

commit 211291126698c8f047617565b2e2e7f822f86354 upstream.

It appears that smart data retrieval has been broken the since the
initial implementation.  Fix the payload size to be 128-bytes per the
specification.
