Yes, looks like there might be problem here.  However, is there any
way to consolidate the "cancel and wait for done" code in one place,
rather than just cut-and-pasting it from ipoib_stop_thread()?

This could explain the oops in ipoib_mcast_sendonly_join_complete(),
but only if a send-only group is being replaced by a full-member
join.  Is Eli's test doing that?
