virtio-gpu: fix crashes upon warm reboot with vga mode
With vga=775 on the Linux command line a first boot of the VM running Linux works fine. After a warm reboot it crashes during Linux boot. Before that, valgrind points out bad memory write to console surface. The VGA code is not aware that virtio-gpu got a message surface scanout when the display is disabled. Let's reset VGA graphic mode when it is the case, so that a new display surface is created when doing further VGA operations. https://bugs.launchpad.net/qemu/+bug/1784900/ Reported-by: Stefan Berger <stefanb@linux.vnet.ibm.com> Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Michael S.
