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

drivers/gpu/drm/amd/amdgpu/../pm/powerplay/hwmgr/ppevvmath.h: In function ‘fMultiply’:
drivers/gpu/drm/amd/amdgpu/../pm/powerplay/hwmgr/ppevvmath.h:336:22: warning: variable ‘Y_LessThanOne’ set but not used [-Wunused-but-set-variable]
drivers/gpu/drm/amd/amdgpu/../pm/powerplay/hwmgr/ppevvmath.h:336:7: warning: variable ‘X_LessThanOne’ set but not used [-Wunused-but-set-variable]
