Gao Feng b5ed572a1b netfilter: nf_nat_snmp: Fix panic when snmp_trap_helper fails to register ...

[ Upstream commit 75c689dca9 ]

In the commit 93557f53e1 ("netfilter: nf_conntrack: nf_conntrack snmp
helper"), 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.
