link_path_walk: kill the recursion absolutely straightforward now - the only variables we need to preserve across the recursive call are name, link and cookie, and recursion depth is limited (and can is equal to nd->depth). So arrange an array of triples to hold instances of those and be done with that. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
