Fix bugs when VM shutdown with virtio-gpu unplugged

Virtio-gpu malloc memory for the queue when it realized, but the queues was not
released when it unrealized, which resulting in a memory leak. In addition,
vm_change_state_handler is not cleaned up, which is related to vdev and will
lead to segmentation fault when VM shutdown.
