If nop tracer is selected, some old entries from the previous tracer
could still be enqueued. Tracing have to be reset.

Steven Noonan fb1b6d8b51 ftrace: add nop tracer 
A no-op tracer which can serve two purposes:

 1. A template for development of a new tracer.
 2. A convenient way to see ftrace_printk() calls without
    an irrelevant trace making the output messy.
