vtkHyperStreamline seg fault when input data has no scalar array

This issue was created automatically from an original Mantis Issue. Further discussion may take place here.

Below is the relevant code in Filters/General/vtkHyperStreamline.cxx:

vtkDataArray *inScalars = NULL;

inScalars = pd->GetScalars(); //pd has no scalar, so inScalars is NULL

cellScalars = vtkDataArray::CreateDataArray(inScalars->GetDataType()); //Seg faults

A patch for it is attached.
