The driver should avoid calling ib_sa_free_multicast on the mcast->mc object until it finishes its initialization state. Otherwise we can crash when ipoib_mcast_dev_flush() attempts to use the uninitialized multicast object. Instead, only call wait_for_completion() for multicast entries that started the join process, meaning that ib_sa_join_multicast() finished.
