tracing: Fix compile issue for trace_sched_wakeup.c 

The function start_func_tracer() was incorrectly added in the
 #ifdef CONFIG_FUNCTION_TRACER condition, but is still used even
when function tracing is not enabled.

The calls to register_ftrace_function() and register_ftrace_graph()
become nops (and their arguments are even ignored), thus there is
no reason to hide start_func_tracer() when function tracing is
not enabled.
