[cares] Suppress a Wunused-function warning
This function is morally static, but exposed for testing, and happens
to be unused with our configuration. It is thus actually unused when
not building tests.
This seems the clearest way to suppress the warning, and seems
preferable to a binary-wide or even file-wide compiler flag toggle.
Test: built and observed no more warning
