tracing/osnoise: Fix notify new tracing_max_latency
commit
d3cba7f02cd82118c32651c73374d8a5a459d9a6 upstream.
osnoise/timerlat tracers are reporting new max latency on instances
where the tracing is off, creating inconsistencies between the max
reported values in the trace and in the tracing_max_latency. Thus
only report new tracing_max_latency on active tracing instances.
