tracing/timerlat: Notify new max thread latency
timerlat is not reporting a new tracing_max_latency for the thread
latency. The reason is that it is not calling notify_new_max_latency()
function after the new thread latency is sampled.
Call notify_new_max_latency() after computing the thread latency.
