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.
