sd-network: when the LLMNR setting is not known for an interface consider that as ENODATA

ENODATA should be returned whenever we have no idea about something. A
missing LLMNR setting can only really happen during upgrades, in whichc
ase we really have no idea, so let's turn this into another ENODATA
case.
