[PATCH v1 1/2] bus/cdx: fix empty device string in error message

[Anatoly Burakov <anatoly.burakov@intel.com>]

The variable cdx_addr is a stack-allocated zero-initialized char array, but
it is never used anywhere, except as part of error message out. The
intention is to display device name, so fix the code to reflect that.
