splunk.HandleHTTPCode always returns an error for any codes other than 2xx. So, the removed condition is always true. The body isn't read for http.StatusTooManyRequests and http.StatusServiceUnavailable error codes anyway. It's only read for http.StatusBadRequest, http.StatusUnauthorized and explicitly drained for 2xx.

I kept the existing behavior of returning the draining errors, but this is wrong. Response body draining errors should not be considered data delivery failures which trigger the retry mechanism by default. I'll fix it in a follow-up PR.

Another fix to do as a follow-up is to ensure the body is drained for all error codes except for http.StatusTooManyRequests and http.StatusServiceUnavailable.

`splunk.HandleHTTPCode` always returns an error for any codes other than 2xx. So the removed condition is always true and we always drain the response body
