    avformat/http: return EIO if s->hd is NULL
    
    This could conceivably happen currently if the user tries reading more
    bytes after the last chunk has already been received. In this case,
    we currently segfault - but simply returning AVERROR(EIO) seems more
    reasonable and lets the higher end retry the connection in this case.
