Description:
NdbScanOperation overrides of getBlobHandle() do not deal with bad column names or numbers well - they are mapped to NULLs which can then cause a crash.

How to repeat:
Attempt to obtain a Blob handle from a Scan operation using a bad column name or number.

Suggested fix:
Add error handling to these methods.

      Bug#40241 : NDBAPI : NdbScanOperation::getBlobHandle() fails with incorrect col names/nums
      
      Scan operation getBlobHandle() methods have insufficient checks for bad
      column names + numbers
      
      New testcase to verify behaviour.
