pdf writen length patch

I got this message on this sample: 0018065471. Valgrind complains too, no crashes though.
Looks like it is due to this:
                       buf = q;
                       inflateEnd(&stream);
                       len -= q - buf;

q == buf, so len is obviously not adjusted at all.

Patch attached.
