[PATCH v2] selftests/powerpc/papr-vpd: Fix missing variable initialization

From: Nathan Lynch <nathanl at linux.ibm.com>

The "close handle without consuming VPD" testcase has inconsistent
results because it fails to initialize the location code object it
passes to ioctl() to create a VPD handle. Initialize the location code
to the empty string as intended.
