[dynamo] Remove redundant recompile call (#100084)
A single call to the `GraphModule.recompile` function occurs after the `GraphModule` has been constructed.
https://github.com/pytorch/pytorch/blob/62f9189d9d6ad1578c1bfddd17d45dc132e4b9b6/torch/_dynamo/output_graph.py#L754-L755
However, the recompile function has already been called once during construction, so this call should be redundant.
```
call stack:
recompile, graph_module.py:644
graph, graph_module.py:411
__setattr__, module.py:1674
__init__, graph_module.py:370
compile_and_call_fx_graph, output_graph.py:754
...
```
So maybe it can be deleted.
