This patch removes a call to
relay_key_is_unavailable_() that is only called when Tor is compiled
without relay support.
Unfortunately, the non-fatal assertion causes a BUG log message to appear for clients when they start up without relay support for each CPU worker we spawn. This makes it spotting issues during bootstrap harder particularly for our iOS developers.
Since the call sites to
values already, we do not think this will be an issue later on.
