I doubt this is the right solution. It certainly
could fix this particular situation but my main
point was packets shouldn't get into kernel
receive queues with skb->dev not IFF_UP.

I think you misunderstood.  The device certainly is IFF_UP.  What
happens is that the multicast spin locks are set up too late:

Could you explain? I can see some inet_rtm_newaddr
interrupted. For me it could be e.g.:

after
vconfig add eth0 9

ip addr add dev eth0.9 ...

before
ip link set dev eth0.9 up
