[PATCH] knfsd: fix setattr-on-symlink error return
This is a somewhat cosmetic fix to keep the SpecFS validation test from complaining. SpecFS want's to try chmod on symlinks, and ext3 and reiser (at least) return ENOTSUPP. Probably both sides are being silly, but it is easiest to simply make it a non-issue and filter out chmod requests on symlinks at the nfsd level.
