UPSTREAM: drm/virtio: Remove incorrect kfree()

Browse Source 
The virtio_gpu_output is a member of struct virtio_gpu_device
and is not a dynamically-allocated chunk, so it's wrong to kfree() it.
Removing it fixes a memory corruption BUG() that can be triggered
when the virtio-gpu driver is removed.
