Why do we need this?

In ServiceWorkerRegistrationNotifications::showNotification() you're using
RefPtr<>.release(), which gives us a PassRefPtr, and therefore should hit the
normal constructor.

This function is for sending "data" in non-persistent notification.
but non-persistance do not use data in WebSerializedScriptValue anymore.
So, I'll remove this. 

+    : m_private(value)
+{
+}
+
 WebSerializedScriptValue& WebSerializedScriptValue::operator=(const PassRefPtr<SerializedScriptValue>& value)
 {
     m_private = value;
     return *this;
 }
 
 WebSerializedScriptValue::operator PassRefPtr<SerializedScriptValue>() const
 {
     return m_private.get();
 }
 
 } // namespace blink
