guest-image-tools: autoconfigure networking: hipersockets nic offline

[Andreas Scheuring]

Started a DPM partition with 2 networks. One OSA and one Hipersockets backed network.
Both NICs got grouped correctly, but only the OSA NIC is "online".

Debug data:

[Andreas Scheuring (andreas-scheuring)]

Starting a new instance worked. I remember I've seen this in the past. The workaround was to delete and add the NIC via the HMC again... So this is not a problem of our dpm code - closing the issue.
