Upstream: call ngx_http_run_posted_requests() on resolve errors.

If proxy_pass to a host with dynamic resolution was used to handle
a subrequest, and host resolution failed, the main request wasn't run
till something else happened on the connection.  E.g. request to "/zzz"
with the following configuration hanged:

    addition_types *;
    resolver 8.8.8.8;

    location /test {
        set $ihost xxx;
        proxy_pass http://$ihost;
    }

    location /zzz {
      add_after_body /test;
      return 200 "test";
    }
