<title>drm/virtio: remove _unlocked suffix in drm_gem_object_put_unlocked</title>

<content type='text'>
Spelling out _unlocked for each and every driver is a annoying.
Especially if we consider how many drivers, do not know (or need to)
about the horror stories involving struct_mutex.

Just drop the suffix. It makes the API cleaner.

Done via the following script:

__from=drm_gem_object_put_unlocked
__to=drm_gem_object_put
for __file in $(git grep --name-only $__from); do
  sed -i  "s/$__from/$__to/g" $__file;
done

If 3D is enabled, but userspace requests a dumb buffer, we will
call CTX_ATTACH_RESOURCE before actually creating the context.

For 3D buffers, virtio_gpu_gem_object_open notifies.
We can have the same behavior for dumb buffer.

v2: virtio_gpu_gem_object_open always notifies
v3: avoid boolean variable

<content type='text'>
Move object release into a separate worker.  Releasing objects requires
sending commands to the host.  Doing that in the dequeue worker will
cause deadlocks in case the command queue gets filled up, because the
dequeue worker is also the one which will free up slots in the command
queue.
