[PATCH 1/2] tracing: Exit out immediately after update_marker_trace()

[Steven Rostedt]

From: Steven Rostedt <rostedt@xxxxxxxxxxx>

The call to update_marker_trace() in set_tracer_flag() performs the update
to the tr->trace_flags. There's no reason to perform it again after it is
called. Return immediately instead.
