I unfortunately don't see a way to remove it, but we should keep
thinking about it. Can you please check if the attached patch is
correct? It should exclude all packets handled by bridge-netfilter
from having their conntrack reference dropped. I didn't add nf_reset()'s
to the bridging code because with tc actions the packets can end up
anywhere else anyway, and this will hopefully get fixed right sometime.

BTW. this line from ip_sabotage_out() looks wrong, it will clear all
flags instead of setting the BRNF_DONT_TAKE_PARENT flag (second
patch):

                        nf_bridge->mask &= BRNF_DONT_TAKE_PARENT;
