This an incremental refactor towards multiple dma-fence contexts
in virtio-gpu.  Since all fences are still allocated using
&virtio_gpu_fence_driver.context, nothing should break and every
processed fence will be signaled.

The overall idea is every 3D context can allocate a number of
dma-fence contexts.  Each dma-fence context refers to it's own
timeline.

For example, consider the following case where virgl submits
commands to the GPU (fence ids 1, 3) and does a metadata query with
the CPU (fence id 5).  In a different process, gfxstream submits
commands to the GPU (fence ids 2, 4).

fence_id (&dma_fence.seqno)       | 1 2 3 4 5
----------------------------------|-----------
fence_ctx 0 (virgl gpu)           | 1   3
fence_ctx 1 (virgl metadata query)|         5
fence_ctx 2 (gfxstream gpu)       |   2   4

With multiple fence contexts, we can wait for the metadata query
to finish without waiting for the virgl gpu to finish.  virgl gpu
does not have to wait for gfxstream gpu.  The fence id still is the
monotonically increasing sequence number, but it's only revelant to
the specific dma-fence context.

To fully enable this feature, we'll need to:
  - have each 3d context allocate a number of fence contexts. Not
    too hard with explicit context initialization on the horizon.
  - have guest userspace specify fence context when performing
    ioctls.
  - tag each fence emitted to the host with the fence context
    information.  virtio_gpu_ctrl_hdr has padding + flags available,
    so that should be easy.

This change goes in the direction specified above, by:
  - looking up the virtgpu_fence given a fence_id
  - signalling all prior fences in a given context
  - signalling current fence

virtio_gpu_fence_event_process sets the last_fence_id and
subsequently calls dma_fence_signal_locked(..).

dma_fence_signal_locked(..) sets DMA_FENCE_FLAG_SIGNALED_BIT,
which is actually checked before &dma_fence_ops.(*signaled) is
called.

The check for last_fence_id is therefore a bit redundant, and
it will not be sufficient to check the last_fence_id for multiple
synchronization timelines.  Remove it.
