log: call vsnprintf only when it is needed to emit trace Reduce the log overhead when the traces are filtered, by moving the vsnprintf call from _log() to log_dispatch(). This patch avoids the printf treatment when LOG features is activated, but trace is filtered, for example when MAX_LOG_LEVEL=8 and LOG_DEFAULT_LEVEL=6.
