Self-NAK, my torture tests uncovered (a rather obvious) locking issue with the dump
code. The src groups will have to be traversed with RCU, and thus RCU-friendly
since the mdb dump code doesn't acquire multicast_lock and we don't want to block
IGMP processing.

I'll wait with v2 to see if there are any other comments.

Thanks,
 Nik
