HFS+: fix unlink of links
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. Signed-off-by: Roman Zippel <zippel@linux-m68k.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
