A couple of hotplug issues with the old monitor


It crashes with an assertion failure when hot-plugging without ACPI enabled.
Previously this worked, but that was perhaps just by luck rather than 
design. 

$ /home/berrange/usr/qemu-git/bin/qemu -monitor stdio  -no-acpi
QEMU 0.11.50 monitor - type 'help' for more information
(qemu) pci_add pci_addr=auto storage file=/home/berrange/mcdboot.img,if=virtio
qemu: /home/berrange/src/external/qemu/hw/qdev.c:109: qdev_create: Assertion 
`bus->allow_hotplug' failed.
Aborted (core dumped)


It will also abort when you attempt to add the 28th extra device, but this
isn't a regression - it has always crashed & burned this way.

In both cases though I'd expect an error to be returned to the monitor
client not an assertion failure
