udf: potential integer overflow
bloc->logicalBlockNum is unsigned so it's never less than zero.
When I saw that, it made me worry that "bloc->logicalBlockNum + count"
could overflow. That's why I changed the check for less than zero
to an overflow check. (The test works because "count" is also
unsigned.)
