Fix a false positive in invalid CAS detection that when the last data stored in CAS just fits inside the DataPool, validation is erroneously think the data stored pass the end of the storage.
The error happens when the size of the data is alignment - 1, as the null termination padding will make the end of the data matches the end of the data pool.
