[PATCH] spapr: Fix Coverity warning while validating nvdimm options

[Shivaprasad G Bhat]

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.
