This variable isn't read and written to with proper locking, so it is racy. Instead of using an unlocked bool use presence in the mc->list The caller could race rdma_join_multicast with rdma_leave_multicast which would leak a mc join and cause a use after free of mc. Instead, do not add the mc to the list until it has completed initialization, all mcs on the list require leaving.
