Log:
[USETUP]
- Don't hardcode buffer string size in GetPartTypeStringFromPartitionType calls.
- Possibly check whether the first character of the PartTypeString string is NULL before
printing a generic partition information in case the partition type is unknown. We might
check instead for the STRING_FORMATUNKNOWN string...
- Don't check for PartTypeString being NULL since it's not a pointer. CID #1363481
and CID #1363494.
