[PATCH] drm/virtio: Remove redundant return type
virtio_gpu_fence_emit() always returns 0, since it
has no error paths.
Consequently no calls for virtio_gpu_fence_emit()
use the return value, and it can be removed.

[PATCH 1/2] drm/virtio: fence: pass plain pointer
Since commit "9fdd90c0f4 drm/virtio: add virtio_gpu_alloc_fence()"
fences are not allocated any more by virtio_gpu_fence_emit(). So there
is no need to pass down a reference to the fence pointer, a plain
pointer is enough now.
Convert virtio_gpu_fence_emit() and callers.

[PATCH v6 08/18] drm/virtio: rework virtio_gpu_execbuffer_ioctl fencing
....
Stop using ttm helpers, use the virtio_gpu_array_* helpers (which work
on the reservation objects directly) instead.
New workflow:
(1) All gem objects needed by a command are added to a
virtio_gpu_object_array.
(2) All reservation objects will be locked (virtio_gpu_array_lock_resv).
(3) virtio_gpu_fence_emit() completes fence initialization.
(4) fence gets added to the objects, reservation objects are unlocked
(virtio_gpu_array_add_fence, virtio_gpu_array_unlock_resv).
(5) virtio command is submitted to the host.
