qxl: don't render stuff when the vm is stopped.
This patch fixes the local qxl renderer to not kick spice-server in case the vm is stopped. First it is largely pointless because we ask spice-server to process all not-yet processed commands when the vm is stopped, so there isn't much do do anyway. Second we avoid triggering an assert in spice-server. The patch makes sure we still honor redraw requests, even if we don't ask spice-server for updates. This is needed to handle displaysurface changes with a stopped vm correctly. With this patch applied it is possible to take screen shots (via screendump monitor command) from a qxl gpu even in case the guest is stopped. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
