mpegvideo: allocate sufficiently large scratch buffer for interlaced vid
MPV_decode_mb_internal needs 3 * 16 * linesize bytes of scratch buffer
For interlaced content, linesize is multiplied by two after the allocation
of the scratch buffer, and the dest_cr pointer ends past the buffer.
This patch makes ff_mpv_frame_size_alloc allocate a total of
(aligned line_size) * 2 * 16 * 3 bytes, which suffices even for the
interlaced case.
