Secondary displays in multihead setups are allowed to have a NULL DisplaySurface. Typically user interfaces handle this by hiding the window which shows the display in question. This isn't an option for vnc though because it simply hasn't a concept of windows or outputs. So handle the situation by showing a placeholder DisplaySurface instead. Also check in console_select whenever a surface is preset in the first place before requesting an update. This fixes a segfault which can be triggered by switching to an unused display (via vtrl-alt-<nr>) in a multihead setup, for example using -device virtio-vga,max_outputs=2.
