HFS+: fix unlink of links
upstream commit: 76b0c26af2736b7e5b87e6ed7ab63901483d5736
Some time ago while attempting to handle invalid link counts, I botched
the unlink of links itself, so this patch fixes this now correctly, so
that only the link count of nodes that don't point to links is ignored.
Thanks to Vlado Plaga <rechner@vlado-do.de> to notify me of this
problem.
