In PQsendQueryStart(), avoid leaking any left-over async result.
Ordinarily there would not be an async result sitting around at thispoint, but it appears that in corner cases there can be. Consideringall the work we're about to launch, it's hardly going to cost anythingnoticeable to check.It's been like this forever, so back-patch to all supported branches.Report: <CAD-Qf1eLUtBOTPXyFQGW-4eEsop31tVVdZPu4kL9pbQ6tJPO8g@mail.gmail.com>
