Peter Zijlstra a77353e5eb irq_work: Remove BUG_ON in irq_work_run() ...

Because of a collision with 8d056c48e4 ("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.
