In the commit ("netfilter: nf_conntrack: nf_conntrack snmp helper"),

   Need to specify the 12-digit SHA1 ID as well.

the snmp_helper is replaced by nf_nat_snmp_hook. So the snmp_helper
is never registered. But it still tries to unregister the snmp_helper,
it could cause the panic.

Now remove the useless snmp_helper and the unregister call in the
error handler.

Fixes: 93557f53e1fb ("netfilter: nf_conntrack: nf_conntrack snmp helper")
