[PATCH] dcookies.c: use proper refcounting functions
Dcookies shouldn't play with the internals of dentry and vfsmnt refcounting. It defeats grepping, and is prone to break if implementation details change. In addition the function doesn't even seem to be performance critical: it calls kmem_cache_alloc().
