Change the *os.File{} dereference call to an &os.File{} pointer

Reproduce the issue with the provided OpenAPI requestBody and the v6.0.1 go-server generation command. Trace the go-server templates or generator entry points that render binary file request bodies, then compile the generated endpoint to verify the invalid indirect is gone and the resulting pointer initialization is valid.
