Fix comment error in TensorIterator.cpp (#100227)
Fixes comment error in TensorIterator.cpp
I believe there is an error in the comment, based on the following code snippet
```c++
if (shape0 * stride[dim0] != stride[dim1]) {
return false;
}
```
I have corrected the comment accordingly. Please let me know if any further action is required.
