qdev-monitor: Set properties after parent is assigned in device_add
Test steps:
(qemu) device_add e1000,addr=adsf
Property 'e1000.addr' doesn't take value 'adsf'
(qemu) info qtree
Then qemu crashed.
Currently we set a link to the new device from its parent bus, but the
device hasn't been added to QOM tree yet. When it fails to set properties,
object_unparent() can't clean up the device.
Delay setting of device properties until the device has been added to
the QOM composition tree. This way, when setting a property fails,
object_unparent() can clean up the device properly.
