jeff 9e1f35189b - Fix a leaked reference to a vnode via v_dd. We rely on cache_purge() and 
cache_zap() to clear the v_dd pointers when a directory vnode is forcibly
   discarded.  For this to work, all vnodes with v_dd pointers to a directory
   must also have name cache entries linked via v_cache_dst to that dvp
   otherwise we could not find them at cache_purge() time.  The following
   code snipit could break this guarantee by unlinking a directory before
   fetching it's dotdot.  The dotdot lookup would initialize the v_dd field
   of the unlinked directory which could never be cleared.  To fix this
   we don't initialize v_dd for orphaned vnodes.
        printf("rmdir: %d\n", rmdir("../foo")); /* foo is cwd */
        printf("chdir: %d\n", chdir(".."));
        printf("%s\n", getwd(NULL));
