Avoid implicit conversion to pointer from QWindowsIUPointer

When converting from QWindowsIUPointer<T> to T* we can accidentally
leak pointer when doing assignment operation such as: var_a = var_b.
If var_a is T* and var_b is QWindowsIUPointer<T>, the pointer
is set on var_a without any warning but the reference counting is
incorrect.
