cdev: use more descriptive struct cdev::diskuuid/partuuid
The UUID field has different meanings:
For a master cdev:
- GPT Header DiskGUID if GPT-formatted
- MBR Header NT Disk Signature if MBR-formatted
For a partition cdev:
- GPT UniquePartitionGUID
- MBR Header NT Disk Signature followed by "-${partititon_number}"
Later code will add yet another UUID (Partition Type GUID), so let's
make existing code more readable by using either diskuuid or partuuid as
appropriate.
No functional change.
