trace: factor out "do we want to trace" logic
As we add more tracing areas, this will avoid repeated code. Technically, trace_printf already checks this and will avoid printing if the trace key is not set. However, callers may want to find out early whether or not tracing is enabled so they can avoid doing work in the common non-trace case.
