    x11: Fix iterative INCR property checks
    
    It does not make sense to check for the stream not being closed,
    this might happen multiple times during the lifetime of the stream
    for a single transfer. We want to notify the INCR transfer just
    once.
    
    Check for the explicit conditions that we want, that the remaining
    data is bigger than we can transfer at once, and that we are not
    yet within the INCR transfer.
