drm/virtio: rework virtio_gpu_object_create fencing

Browse source

Rework fencing workflow.  Stop using ttm helpers, use the
virtio_gpu_array_* helpers instead.

Due to using the gem reservation object it is initialized and ready for
use before calling ttm_bo_init.  So we can simply use the standard
fencing workflow and drop the tricky logic which checks whenever the
command is in flight still.

v6: rewrite most of the patch.
