spapr/xive: Set the OS CAM line at reset
When a Virtual Processor is scheduled to run on a HW thread, the
hypervisor pushes its identifier in the OS CAM line. When running with
kernel_irqchip=off, QEMU needs to emulate the same behavior.
Set the OS CAM line when the interrupt presenter of the sPAPR core is
reset. This will also cover the case of hot-plugged CPUs.
This change also has the benefit to remove the use of CPU_FOREACH()
which can be unsafe.
