Aaron Young 45e48809d3 hw/acpi: propagate vcpu hotplug after switch to modern interface 
If a vcpu with an apic-id that is not supported by the legacy
interface (>255) is hot-plugged, the legacy code will dynamically switch
to the modern interface. However, the hotplug event is not forwarded to
the new interface resulting in the vcpu not being fully/properly added
to the machine config. This BUG is evidenced by OVMF when it
it attempts to count the vcpus and reports an inconsistent vcpu count
reported by the fw_cfg interface and the modern hotpug interface.

Fix is to propagate the hotplug event after making the switch from
the legacy interface to the modern interface.
