[PATCH 0/2] drm/virtio: fix control-buffer leaks on queueing errors

Fix two independent cleanup omissions for control buffers that do not
reach the virtqueue.

Patch 1 fixes the reproduced GEM/VMA leak when fbdev damage work races
with device unplug.

Patch 2 fixes the vmalloc_to_sgt() allocation-failure path, found by
code inspection.

Testing:
- Repeated virtio-gpu unbind/rebind no longer triggers the
  drm_mm_takedown warning.
- Built drivers/gpu/drm/virtio/virtgpu_vq.o with W=1.

Yao Kai (2):
  drm/virtio: release object array when device is unplugged
  drm/virtio: free control buffer when scatterlist allocation fails
