Jack Morgenstein e1d50dce5a IPoIB: Test for NULL broadcast object in ipiob_mcast_join_finish() ... We saw a kernel oops in our regression testing when a multicast "join finish" occurred just after the interface was -- this is <https://bugs.openfabrics.org/show_bug.cgi?id=1040>. The test randomly causes the HCA physical port to go down then up. The cause of this is that ipoib_mcast_join_finish() processing happen just after ipoib_mcast_dev_flush() was invoked (in which case the broadcast pointer is NULL). This patch tests for and handles the case where priv->broadcast is NULL.
