Heiko Carstens 2481a87b02 s390/ftrace: optimize function graph caller code
When the function graph tracer is disabled we can skip three additional
instructions. So let's just do this.

So if function tracing is enabled but function graph tracing is
runtime disabled, we get away with a single unconditional branch.
