[quant][fix][fx][graphmode] Fix qconfig setting for fused modules (#71254)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/71254
when we configure linear and relu with the same qconfig, we currently have utility functions to also
generate a qconfig for the fused linear relu module, but this code is not called in correct order before
which resulted in unexpected behaviors. This PR fixes the issue. Please see test case for more details.
(Test case is from Supriya)
