vt: fix broken display when running aptitude
If you run aptitude on framebuffer console, the display is corrupted. The corruption is caused by the commit d8ae7242. The patch adds "offset" to "start" when calling scr_memsetw, but it forgets to do the same addition on a subsequent call to do_update_region.
