    encoder: h264: fix ip_period value in sequence parameter.
    
    The VAEncSequenceParameterBuffer.ip_period value reprents the distance
    between the I-frame and the next P-frame. So, this also accounts for
    any additional B-frame in the middle of it.
    
    This fixes rate control heuristics for certain VA drivers.
