avcodec/mips: Fix failed case: hevc-conformance-AMP_A_Samsung_* when enable msa

The AV_INPUT_BUFFER_PADDING_SIZE has been increased to 64, but the value is still 32
in function ff_hevc_sao_edge_filter_8_msa. So, use AV_INPUT_BUFFER_PADDING_SIZE directly.
Also, use MAX_PB_SIZE directly instead of 64. Fate tests passed.
