sched/pelt: Fix warning and clean up IRQ PELT config
...
Commit 11d4afd4ff667f9b6178ee8c142c36cb78bd84db upstream.
Create a config for enabling irq load tracking in the scheduler.
irq load tracking is useful only when irq or paravirtual time is
accounted but it's only possible with SMP for now.
Also use __maybe_unused to remove the compilation warning in
update_rq_clock_task() that has been introduced by:
