Fixes gcc '-Wunused-but-set-variable' warning:
drivers/video/fbdev/kyro/STG4000OverlayDevice.c: In function
‘SetOverlayViewPort’:
drivers/video/fbdev/kyro/STG4000OverlayDevice.c:334:19: warning:
variable ‘ulScaleRight’ set but not used [-Wunused-but-set-variable]
It is never used, and so can be removed.
