New helper: terminate_walk(). An error has happened during pathname
resolution and we either drop nd->path or terminate RCU, depending
the mode we had been in. After that, nd is essentially empty.
Switch link_path_walk() to using that for cleanup.
Now the top-level logics in link_path_walk() is back to sanity. RCU
dependencies are in the lower-level functions.
