monitor: allow device_del to accept QOM paths
Currently device_del requires that the client provide the
device short ID. device_add allows devices to be created
without giving an ID, at which point there is no way to
delete them with device_del. The QOM object path, however,
provides an alternative way to identify the devices.
Allowing device_del to accept an object path ensures all
devices are deletable regardless of whether they have an
ID.
(qemu) device_add usb-mouse
(qemu) qom-list /machine/peripheral-anon
device[0] (child<usb-mouse>)
type (string)
(qemu) device_del /machine/peripheral-anon/device[0]
Devices are required to be marked as hotpluggable
otherwise an error is raised
(qemu) device_del /machine/unattached/device[4]
Device 'PIIX3' does not support hotplugging
