drm/mgag200: Fix value in <VBLKSTR> register
Fix an off-by-one error when setting the vblanking start in
<VBLKSTR>. Commit d6460bd52c27 ("drm/mgag200: Add dedicated
variables for blanking fields") switched the value from
crtc_vdisplay to crtc_vblank_start, which DRM helpers copy
from the former. The commit missed to subtract one though.
