[pve-devel] [PATCH v2 qemu-server] cpu config: die on hotplug of non x86_64 CPUs

When attempting a CPU hotplug on an architecture other than x86_64, die
with a clean error instead of attempting a hotplug with a known
non-working device command line. Also move the corresponding FIXME up to
the error.
