setup: fix "control reaches end of non-void function" compiler warning

Actually, it is impossible to reach the end of these two functions
without return()ing earlier from one of the switch() statements'
branches. But since the compiler cannot know this and warns about it,
and since this warning can be escalated into an error in later
compiler versions, silence it by return()ing a dummy value at the end
of each function.

Fixes #508
