Improve mismatched storage error message. (#19068)
Summary:
Previously the error message would look like:
```
Attempted to set the storage of a tensor on device cuda:0 to a storage on different device cuda. This is no longer allowed; the devices must match.
```
Now it looks like:
```
Attempted to set the storage of a tensor on device "cuda:0" to a storage on different device "cuda". This is no longer allowed; the devices must match.
```
