[PATCH v2 1/2] domain_conf: remove else after return / goto

[Kristina Hanicova]

The else branches are redundant because the execution will never
reach them if the conditions in the previous 'if' branches are
true.

I think this looks cleaner and is more readable, because having
'else' branch indicates that no return / break / goto is in the
previous branch and the function can reach it.
