Gerd Hoffmann e65294157d vga: fix display update region calculation (split screen) ...

vga display update mis-calculated the region for the dirty bitmap
snapshot in case split screen mode is used.  This can trigger an
assert in cpu_physical_memory_snapshot_get_dirty().

Impact:  DoS for privileged guest users.
