fix(inputs.snmp): Disable OID increase check

[Hipska]

Summary

Some devices don't (always) return OIDs in increasing order and then telegraf logs this error:

E! [inputs.snmp] Error in plugin: agent 10.0.0.1:161: gathering table interface: performing bulk walk for field in_discards: OID not increasing: .1.3.6.1.2.1.2.2.1.13.40014 >= .1.3.6.1.2.1.2.2.1.13.21

Solution: Disable the GoSNMP increase check as Telegraf handles them flawlessly.
