[PATCH 2/3] trace-cmd: don't call stop_threads() if doing latency tracing

[Mark Asselstine <mark.asselstine@windriver.com>]

If we are using a latency tracer we do not call start_threads() we
should therefore not call stop_threads() if 'latency'. Attempting
to call stop_threads() without first calling start_threads() will
cause a segfault since pids will be uninitialized.
