NetworkProcess crashes in WebCoreResourceHandleAsOperationQueueDelegate callbacks

In the "two part" callbacks that do a dispatch_async followed by a dispatch_semaphore_wait the delegate might have been released and destroyed by the time the semaphore returns.

This is bad, and can be fixed with a RetainPtr<> protector.
