drm/udl: Remove struct udl_device.active_fb_16

The udl driver stores the currently active framebuffer to know from
where to accept damage updates.

With the conversion to plane-state damage handling, this is not necessary
any longer. The currently active framebuffer and damaged area are always
stored in the plane state.
