[PULL 13/22] hw/cxl/cxl-cdat: Make ct3_build_cdat() return boolean

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

From: Zhao Liu <zhao1.liu@intel.com>

As error.h suggested, the best practice for callee is to return
something to indicate success / failure.

So make ct3_build_cdat() return boolean, and this is the preparation for
cxl_doe_cdat_init() returning boolean.
