kernel/sched: Add missing SMP thread abort case

Browse source 
The loop in thread abort on SMP where we wait for the results on an
IPI correctly handled the case where a thread running on another CPU
gets its interrupt and self-aborts, but it missed the case where the
other thread pends before receiving the interrupt.
