tracing: Move the tracing_on/off() declarations into CONFIG_TRACING
The tracing_on/off() declarations were under CONFIG_RING_BUFFER, but the functions are now only defined under CONFIG_TRACING as they are specific to ftrace and not the ring buffer. But the declarations were still defined under the ring buffer and this caused the build to fail when CONFIG_RING_BUFFER was set but CONFIG_TRACING was not.
