remove dead code

remove dead code.

in the image-service the result of ListMachines is only used later when doing the lookup via machinesByImage. But after this lookup we have a nested if-construct where the inner "if" is always false as it was checked a few lines above. so the if len(machiens) ... is alway an empty block and can be removed. so the whole Listmachines .

same in network-service as the if err != nil is always false.

Great that you found this. Can't we just remove the inner if-clauses that check the error to make the code behave as it was intended?

ok, code changed so it behaves like the author originally wanted
