IPS_CONFIRMED_BIT is set under nf_conntrack_lock (in __nf_conntrack_confirm()),
we probably want to add a synchronisation under ct->lock as well,
or __nf_ct_refresh_acct() could set ct->timeout.expires to extra_jiffies,
while a different cpu could confirm the conntrack.

Following patch as RFC

A quick test suggests that it seems to works here - thanks Eric!

Patrick, please take a quick look at Eric's fix.  I'd like to
apply it quickly if it looks good to you.

Thanks!
