drm/vgem: Remove unecessary dma_fence_ops

dma_fence_default_wait is the default now, same for the trivial
enable_signaling implementation.

Also remove the ->signaled callback, vgem can't peek ahead with a
fastpath, returning false is the default implementation.

v2: Protect the meaningful space! (Chris)
