irq_work: Remove BUG_ON in irq_work_run()
Because of a collision with 8d056c48 ("CPU hotplug, smp: flush any pending IPI callbacks before CPU offline"), which ends up calling hotplug_cfd()->flush_smp_call_function_queue()->irq_work_run(), which is not from IRQ context. And since that already calls irq_work_run() from the hotplug path, remove our entire hotplug handling.
