A concurrent lookup can find this OPP and increment its reference count while it is still uninitialized, leading to refcount corruption and a potential premature free.  Fix this by initializing -\u003ekref and -\u003eopp_table before making the OPP visible via list_add(). This ensures any concurrent lookup observes a fully initialized object.
