From: Florian Westphal <fw@xxxxxxxxx> When the conntrack module is removed, we call nf_ct_iterate_destroy via nf_ct_l4proto_unregister(). Problem is that nf_conntrack_proto_fini() gets called after the conntrack hash table has already been freed. Just remove the l4proto unregister call, its unecessary as the nf_ct_protos[] array gets free'd right after anyway. v2: add comment wrt. missing unreg call.
