    encoder: h264: refine size of coded buffer.
    
    Refine the heuristic to determine the maximum size of a coded buffer
    to account for the exact number of slices. set_context_info() is the
    last step during codec reconfiguration, no additional change is done
    afterwards, so re-using the num_slices field here is fine.
