xen/smp: unbind irqworkX when unplugging vCPUs.
The git commit 1ff2b0c303698e486f1e0886b4d9876200ef8ca5
"xen: implement IRQ_WORK_VECTOR handler" added the functionality
to have a per-cpu "irqworkX" for the IPI APIC functionality.
However it missed the unbind when a vCPU is unplugged resulting
in an orphaned per-cpu interrupt line for unplugged vCPU:
30: 216 0 xen-dyn-event hvc_console
31: 810 4 xen-dyn-event eth0
32: 29 0 xen-dyn-event blkif
- 36: 0 0 xen-percpu-ipi irqwork2
- 37: 287 0 xen-dyn-event xenbus
+ 36: 287 0 xen-dyn-event xenbus
NMI: 0 0 Non-maskable interrupts
LOC: 0 0 Local timer interrupts
SPU: 0 0 Spurious interrupts
