I was attempting to use the get_device endpoint to determine whether a device existed in LibreNMS as the endpoint is written to return a 404 if the device doesn't exist. But I found that no matter what hostname you gave it a 200 would be returned along with this:

{ "status": "ok", "devices": [ { "vrf_lite_cisco": [], "ip": "" } ] }

get_device depends on device_by_id_cache for a device object, which hits the DB for the device table info and vrf_lite_cisco table info. However, the index 'vrf_lite_cisco' is added to the device object before validating that anything was returned from the DB. 'ip' gets added by processing it with inet6_pton whether or not an IP was returned from the DB.

This commit moves the addition of 'vrf_lite_cisco' in to the block that validates that any vrf rows exist, and adds the same kind of validation to the IP element.
