[PATCH v2 2/2] domain_conf: rewrite if else functions to switch

[Kristina Hanicova]

Pattern of using switch instead of a long if else construction is
used everywhere, so I used it here as well to make the code more
consistent (and remove that else after return). I also included
all the values from the enum.
