QuantWrapper did not correctly apply qconfig to the dequant.
Therefore, if the user first applied qconfig to their module and
then wrapped it with `QuantWrapper`, the dequant would not get
swapped during the convert step.
The fix is to properly apply the qconfig to the dequant.
Test Plan:
```
python test/test_quantization.py TestQuantizeEagerPTQStatic.test_quantwrapper_attaches_qconfig_to_dequant
```
