[Qemu-devel] [PULL 3/4] spice: don't update mm_time when spice-server is stopped.

[Gerd Hoffmann <kraxel@redhat.com>]

Skip mm_time updates (in qxl device memory) in case the guest is stopped.
Guest isn't able to look anyway, and it causes problems with migration.

Also make sure the initial state for spice server is stopped.
