Thomas Gleixner 3cd788c1ee x86/smp: Use static key for reschedule interrupt tracing
It's worth to avoid the extra irq_enter()/irq_exit() pair in the case that
the reschedule interrupt tracepoints are disabled.

Use the static key which indicates that exception tracing is enabled. For
now this key is global. It will be optimized in a later step.
