[vtkusers] Double error check in vtkImageData?

In vtkImageData, GetScalarPointer(x, y, z) error checks by checking if the
coordinates are in the bounds of the image. It then calls
GetArrayPointer(int) which error checks again (with identical code) which
finally returns the results.
What's the reason for this? Is this a mistake? Seems to me the first error
check is not needed.
