Description:
Creating an NdbScanFilter object using an NdbScanOperation object that has not had its readTuples() method called results in a SEGV when later attempting to use the ScanFilter.

How to repeat:
As above

Suggested fix:
Move indication of 'old Api scan' from readTuples() back to getNdbScan/IndexScanOperation() call.
Improve handling of failure to allocate code object.
