compositor: ignore views on other outputs during compositor_accumulate_damage()

Browse Source 
compositor_accumulate_damage() is called for each output during repaint.
The DRM backend will only set keep_buffer for the surfaces that are visible on
the current output. So a buffer_ref is released that may still be needed. When
the output that shows the surface is repainted, the buffer_ref is gone and the
surface cannot be put on a plane.

Ignore all surfaces that are not visible on the current output to avoid this.
