lib: fix coverity unused result warning

There's nothing that can be done here with an error.  Try to make
Coverity understand that this is intentional.

(I don't know if the `(void)` will actually fix the coverity warning,
but I don't really have a better way to figure it out beyond just
getting this merged and waiting for a result...)
