From: Zongmin Zhou
Details:
Currently, when trying to suspend and resume with qxl deviceï¼
there are some error messages after resuming,
eventually caused to black screen and can't be recovered.
The first error message:
[ 64.668577][C3] [drm] driver is in bug mode
This err
Since qxl_io_reset(qdev) will be called immediately
after qxl_ring_create() been called,
and parameter like notify_on_prod will be set to default value.
So the call to qxl_ring_init_hdr() before becomes meaningless.

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.
