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

 drivers/gpu/drm/amd/amdgpu/../display/dc/dce/dce_transform.c: In function ‘dce60_transform_set_scaler’:
 drivers/gpu/drm/amd/amdgpu/../display/dc/dce/dce_transform.c:496:7: warning: variable ‘filter_updated’ set but not used [-Wunused-but-set-variable]
 drivers/gpu/drm/amd/amdgpu/../display/dc/dce/dce_transform.c: In function ‘dce60_transform_set_pixel_storage_depth’:
 drivers/gpu/drm/amd/amdgpu/../display/dc/dce/dce_transform.c:1040:19: warning: variable ‘expan_mode’ set but not used [-Wunused-but-set-variable]
 drivers/gpu/drm/amd/amdgpu/../display/dc/dce/dce_transform.c:1040:6: warning: variable ‘pixel_depth’ set but not used [-Wunused-but-set-variable]
