ui/egl: fix framebuffer reads
Fix egl_fb_read() to use the (destination) surface size instead of the
(source) framebuffer source for glReadPixels. Pass the DisplaySurface
instead of the pixeldata pointer to egl_fb_read() to make this possible.
With that in place framebuffer reads work fine even if the surface and
framebuffer sizes don't match, so we can remove the guest-triggerable
asserts in egl_scanout_flush().
