sched_ext: Fix exit_cpu accuracy for lockup paths
handle_lockup() uses raw_smp_processor_id() for exit_cpu, which is wrong
for two paths:
- scx_hardlockup_irq_workfn() has the hung CPU in a local variable but
irq_work may run elsewhere. Pass the local cpu explicitly.
- scx_rcu_cpu_stall() records the detector CPU rather than the stalled
one. Pass -1 for now. The next patch fixes this properly.
