Fix replaceAtenConvolution for BC. (#44036)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/44036
Running replaceAtenConvolution on older traced model wont work as
_convolution signature has changed and replaceAtenConvolution was
changed to account for that.
But we did not preserve the old behavior during that. This change
restores the old behavior while keeing the new one.
