ole32: Fix DefaultHandler_EnumAdvises.

As per MSDN, if the object has no connections then
IOleObject::EnumAdvises should return a NULL enumerator and S_OK. This
is the case when This->oleAdviseHolder is NULL, so do this and avert a
potential NULL dereference of This->oleAdviseHolder (found by
Coverity).
