drm/virtio: add virtio_gpu_alloc_fence()
Refactor fence creation, add fences to relevant GPU operations and add cursor helper functions.
This removes the potential for allocation failures from the cmd_submit and atomic_commit paths. Now a fence will be allocated first and only after that will we proceed with the rest of the execution.
