[PATCH v5 09/12] drm/virtio: rework virtio_gpu_object_create fencing
Use gem reservation helpers and direct reservation_object_* calls
instead of ttm.
v5: fix fencing (Chia-I Wu).
v3: Due to using the gem reservation object it is initialized and ready
for use before calling ttm_bo_init, so we can also drop the tricky fence
logic which checks whenever the command is in flight still. We can
simply fence our object before submitting the virtio command and be done
with it.

I think this is now after ttm_bo_init, and at that point the object is
visible to lru users and everything. So I do think you need to grab locks
here instead of just incrementing the pin count alone.
It's also I think a bit racy, since ttm_bo_init drops the lock, so someone
might have snuck in and evicted the object already.
