[Qemu-devel] [PULL 18/47] qdev: do not allow to instantiate non hotpluggable device with device_add

["Andreas Färber" <afaerber@suse.de>]

From: Igor Mammedov <imammedo@redhat.com>

It will allow explicitly mark device as not hotpluggable and
avoid its creation with following error at realize time
and destroying it afterwards anyway. Instead of it will
error out even before instance of device is created.
