IVGCVSW-6430 Clear up coverity issues

 * Removed unreachable code
    * break after if else where both branches return
 * Removed unused operations
    * Result of dstPtr++ is unused
 * Fixed possible overflow
    * Axis dimensionSequence assignment can result in overflow where rank
      is not 4
 * Removed use of old-style casts
 * Fixed spelling mistakes in error messages
