Subject: Patch Very Minor to loopback.c

Very minor patch to loopback.c that I noticed while comparing the
dummy.c code to loopback.c code (dummy.c was based on loopback.c).  I
did not see a maintainer in MAINTAINERS in my cursory glance, so I
apologize if this is to the wrong place.  I am testing this patch
right now on my laptop and it appears to be working without issues.
It also compiled without warnings.
