Subject: [patch -master] netfilter: xt_CT: checking for IS_ERR() instead of
NULL
We recently changed this from nf_conntrack_alloc() to nf_ct_tmpl_alloc()
so the error handling needs to changed to check for NULL instead of
IS_ERR().
Fixes: 0838aa7fcfcd ('netfilter: fix netns dependencies with conntrack templates')
