tracing: Have tracing_sched_wakeup_trace() use standard unlock_commit

Steven Rostedt · rostedt · commit 2b70e59043f5 · 2012-10-31T16:45:30.000-04:00
The functon tracing_sched_wakeup_trace() does an open coded unlock
commit and save stack. This is what the trace_nowake_buffer_unlock_commit()
is for.
