When I merged the extension sysctl tables with the main one I forgot to
reset them on netns creation. They currently read/write init_net settings.
Fixes: d912dec12428 ("netfilter: conntrack: merge acct and helper sysctl table
with main one")
Fixes: cb2833ed0044 ("netfilter: conntrack: merge ecache and timestamp sysctl
tables with main one")

Shmulik, could you please check if this fixes the bug for you?
Thanks!
