fix: [farsight_passivedns] Fixed lookup_rdata_name results desclaration

- Getting generator as a list as it is already the
  case for all the other results, so it avoids
  issues to read the results by accidently looping
  through the generator before it is actually
  needed, which would lose the content of the
  generator
- Also removed print that was accidently introduced
  with the last commit
