lavc/arm: dont assign hevc_qpel functions for non-multiple of 8 widths
The assembly is written assuming that the width is a multiple of 8. However the real issue is the functions were errorneously assigned to the 2, 4, 6 & 12 widths. This behaviour never broke the decoder as samples which trigger the functions for these widths have not been found in the wild. This relies on the mappings in ff_hevc_pel_weight[]. Signed-off-by: J.
