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.
