Fix a couple of cases of infinite recursion

[dcci]

I'm not really familiar with this code yet but I hope they make sense to you.

My original intent was that of silencing a clang warning (with -Winfinite-recursion)
warning: all paths through this function will call itself [-Winfinite-recursion].
I don't currently have a working swift compiler as porting to FreeBSD is still a WIP.
Maybe this can wait until I get something working (or somebody else writes a test for this).

This patch looks fine to me. There is no way to write a testcase for this since the functions are apparently dead. A better patch might be to just remove them, but in the absence of that, making them correct seems fine. Thanks!
