libmix: increase DPB_SIZE to handle H264 stream with 16 reference frames.

BZ: 10408

Current DPB_SIZE for H264 is set to 16, if reference frame number reaches maximum 16
and the frame to be decoded is a referencs as well, no left buffer node for current frame
and one reference frame will be replaced, which leads to decoding error due to missing reference.
