    Fix a segfault in ssh2_throttle_all_channels.
    
    ssh2_channel_check_throttle should only be called on channels for
    which c->chan != NULL - that is, only for channels that are not
    delegated to a sharing downstream. But throttle_all_channels was
    calling it for _all_ channels, so if it had the bad luck to be called
    while a sharing downstream was active, ssh2_channel_check_throttle
    would dereference the null c->chan for the first downstream channel it
    found.
