drm/virtio: New fence for every plane update
Having a fence linked to a virtio_gpu_framebuffer in the plane update
sequence would cause conflict when several planes referencing the same
framebuffer (e.g. Xorg screen covering multi-displays configured for an
extended mode) and those planes are updated concurrently. So it is needed
to allocate a fence for every plane state instead of the framebuffer.
