Do not wrap output with input device inside _to_copy (#119868)
Fixing https://github.com/pytorch/pytorch/issues/118790
This diff revert a small part of the code that was introduced in https://github.com/pytorch/pytorch/pull/104689
The PR above added a comment that "In case of dtype promotion, fake tensor converted into tensor"
but its not always the case that a conversion in dtype causes a fake tensor to be a tensor.
When such conversion does not happen we get the following error
```
Creating a new Tensor subclass FakeTensor but the raw Tensor object is already associated to
a python object of type FakeTensor
```
