From: wangmeiling <wangmeilin...@huawei.com>
In the virtio-gpu unrealize process, the vdev structure has been cleaned up.
However, vm_change_state_handler is not cleaned up yet, which is related to
vdev. This handler will be cleaned up when VM shutdown, but the vdev is
already a null pointer at this time, this will lead to segmentation fault.
