lavc/vc1dsp: match C block layout in inv_trans_4x4_rvv
Although checkasm does not verify this, the decoder requires that the transform updates the input block exactly like the C code does. This fixes vc1-ism, vc1_ilaced_twomv, vc1_sa00040, vc1_sa10091, vc1_sa10143, vc1_sa20021, vc1test_smm0005 and wmv3-drm-dec tests.
