Pick up the correct source rectangle from framebuffer.
Without this multihead setups are not working correctly.

Additionally, I had to modify the page_flip() function to take the
plane source coordinates for virgl/3d multihead to work. Feel free to
squash.

This is in progress of being sorted, by dropping the
virtio_gpu_page_flip function altogether in favor of atomic helpers,
which will use the (already fixed) plane callbacks instead.
See nonblocking commit support patches by Daniel Vetter on this list.
