Subject: http_proxy: only wait for writable socket while sending request

Otherwise it would wait socket writability even after the entire CONNECT
request has sent and make curl basically busy-loop while waiting for a
response to come back.

The previous fix attempt in #7484 (c27a70a591a4) was inadequate.
