commit 2cd7b6f08bc4 ("drm/virtio: add in/out fence support
for explicit synchronization") deleted dma_fence_put(),
which will cause the memory leak. To balance the reference
count initialized when allocating fence, dma_fence_put()
should not be deleted.
Fixes: 2cd7b6f08bc4 ("drm/virtio: add in/out fence support for explicit
synchronization")
