    client: Don't update smoother while corked
    
    This prevents the smoother attached to the stream clock from being
    updated while the stream is corked, which in turn ensures that once
    corking is completed, pa_stream_get_time() always returns the same value
    until the stream is uncorked - i.e., the clock does not advance when the
    client believes that it will not.
    
    The actual call to pa_smoother_put() happens on things like stream
    suspend/unsuspend, which trigger timing updates. This changes the
    smoother coefficients, which means that a call to pa_smoother_get() for
    the same value of 'x' can return different values before and after a
    timing update.
