Fixes the following W=1 kernel build warning(s):

 drivers/video/fbdev/sis/init.c: In function ‘SiS_SetCRT1ModeRegs’:
 drivers/video/fbdev/sis/init.c:2651:49: warning: variable ‘resindex’ set but not used [-Wunused-but-set-variable]
 drivers/video/fbdev/sis/init.c: In function ‘SiS_Generic_ConvertCRData’:
 drivers/video/fbdev/sis/init.c:3544:19: warning: variable ‘A’ set but not used [-Wunused-but-set-variable]
 drivers/video/fbdev/sis/init.c:3542:34: warning: variable ‘VBS’ set but not used [-Wunused-but-set-variable]
