[webdriver] Reuse the HTTP connection to the WebDriver remote end

HTTPWireProtocol has an internal flag _last_request_is_blocked to tell if the underlying HTTP connection is unusable and should be thrown away (see #21889). However, the transport sets the flag too early, which has the effect of transparently closing and reopening the connection before every request.

This is wasteful and appears to sometimes exhaust the host machine's usable ports in long test runs (https://crbug.com/343720396). Set the flag after it's checked to avoid unnecessary connection closures.
