tracing: use nowakeup version of commit for function event trace tests
The startup tests for the event tracer also runs with the function tracer enabled. The "wakeup" version of the trace commit was used which can grab spinlocks. If a task was preempted by an NMI that called a function being traced, it could deadlock due to the function tracer trying to grab the same lock. Thanks to Frederic Weisbecker for pointing out where the bug was.
