The wakeup tracer has three types of function tracers. Normal
function tracer, function graph entry, and function graph return.
Each of these use a complex dance to prevent recursion and whether
to trace the data or not (depending on the wake_task variable).
This patch moves the duplicate code into a single routine, to
prevent future mistakes with modifying duplicate complex code.
