Fixes write_error loop from bail_out function

I think you can use the property hereself.request.ip

[seemethere]

Well in the example that we had seen from the issue self.parser was still None so I'd be wary of if self.request was filled out correctly as well. It's just a safe way of doing it.

@seemethere I was going to use another try/except here, and just log in the exception, instead of trying to write. Are there any other exceptions that could occur during self_write within bail_out and lead to a circular exception? If there are, the try/except makes more sense imo.

[r0fls]

I would also think a try/except would be faster than checking the transport.is_closing() method each time, but I don't have a working test case for this. The issue didn't actually throw any exception for me ... maybe I did something wrong.

You might need to run it through wrk to replicate the issue.

[r0fls]

I saw almost no benefit to using try/except instead, so let's use this for now.
