spapr: Fix Coverity warning while validating nvdimm options
Fixes Coverity issue,
CID 1419883: Error handling issues (CHECKED_RETURN)
Calling "qemu_uuid_parse" without checking return value
nvdimm_set_uuid() already verifies if the user provided uuid is valid or
not. So, need to check for the validity during pre-plug validation again.
As this a false positive in this case, assert if not valid to be safe.
Also, error_abort if QOM accessor encounters error while fetching the uuid
property.
