<h3>Log Message</h3>
<pre>Notify client immediately if network session doesn't exist for a synchronous XHR load.
https://bugs.webkit.org/show_bug.cgi?id=158239
<rdar://problem/26344251>
Patch by Yongjun Zhang <yongjun_zhang@apple.com> on 2016-06-01
Reviewed by Brady Eidson.
For a synchronous XHR load, if the network session doesn't exist, we should notify NetworkLoadClient.
Otherwise the Web process could hang when waiting for the synchronous load to finish.

(WebKit::NetworkLoad::NetworkLoad):</pre>
