Collectd doesn't store any data when encountering a genErr SNMP error

Description

I've a SNMP agent which generates an snmp packet error when requested an invalid OID.

This causes collectd to not store any SNMP data for this node.

Collectd should still store other datacollection groups.

Here's the logs in collectd:

2016-10-05 15:23:31,313 WARN [DefaultUDPTransportMapping_0.0.0.0/0] o.o.n.c.SnmpNodeCollector: genErr collecting data for node 10.21.0.3: Received genErr requesting oid .1.3.6.1.4.1.193.113.1.1.1.1.1.3.

Marking column is finished.

Here's the error shown when snmpwalking one of this OID:

root@opennms:/etc/opennms/datacollection# snmpwalk -v 3 -a SHA -A xxxxxxxxxxxxx -x AES -X xxxxxxxxxxx -u opennms -l AuthPriv 10.21.0.3 .1.3.6.1.4.1.193.113.1.1 Error in packet. Reason: (genError) A general failure occured Failed object: SNMPv2-SMI::enterprises.193.113.1.1 SNMPv2-SMI::enterprises.193.113.1.1 = No Such Object available on this agent at this OID

The agent replies correctly for other OID's:

root@opennms:/etc/opennms/datacollection# snmpwalk -On -v 3 -a SHA -A xxxxxxxxxxxxx -x AES -X xxxxxxxxxxxxxxx -u opennms -l AuthPriv 10.21.0.3 sysObjectID .1.3.6.1.2.1.1.2.0 = OID: .1.3.6.1.4.1.8072.3.2.10

Ericsson datacollection-group issue created: https://issues.opennms.org/browse/NMS-8788

since it seems there's a problem with the "Ericsson" datacollection-group, I'll create another issue for this later.
