IPoIB: Fix another send-only join race
Further, there's an additional issue that I saw in testing:
ipoib_mcast_send may get called when priv->broadcast is NULL (e.g. if
the device was downed and then upped internally because of a port
event).
If this happends and the send-only join request gets completed before
priv->broadcast is set, we get an oops.
