Summary: this gates calling quic logging only until the logger is on. The static trace probes cause the toStrings to be invoked even though the probes are not active. This is not great. We haven't used the probes in a very long time, so let's just disable them Reviewed By: mjoras Differential Revision: D18758993 fbshipit-source-id: 4ccce3374cbf431607fc8d5fb5a29410c7f94529
