QNAM HTTP: Fix crazy crash when exiting application

This fixes a crash in tst_qnetworkreply and in some QtWebKit
based browsers.
It was related to adding a QPointer on an already
deleted QHttpNetworkConnection object. By converting
an existing normal pointer to a QPointer we set
it a 0-pointer and are safe.
