[ Upstream commit 0e8b9f258baed25f1c5672613699247c76b007b5 ]
The allocated memory for qdev->dumb_heads should be released in qxl_destroy_monitors_object before qxl suspend. otherwise,qxl_create_monitors_object will be called to reallocate memory for qdev->dumb_heads after qxl resume, it will cause memory leak.
