tracing/osnoise: Use start/stop_per_cpu_kthreads() on osnoise_cpus_write()
When writing a new CPU mask via osnoise/cpus, if the tracer is running,
the workload is restarted to follow the new cpumask. The restart is
currently done using osnoise_workload_start/stop(), which disables the
workload *and* the instrumentation. However, disabling the
instrumentation is not necessary.
Calling start/stop_per_cpu_kthreads() is enough to apply the new
osnoise/cpus config.
