Good point. It should never happen because the "ip command" would not
allow autojoin with a non multicast address. However in v1 of the
patch I was doing this via a workqueue and could not return an error.
Its not a problem anymore since ip_mc_config can return an error. I
will remove it. I will wait till tomorrow to see if there are any
other comments.

I was about to send in a patchset that adds UDP bearer support for TIPC, 
after rebasing it on top of this i could remove all deferred setup work
for mcast.
Thanks!
