switch try_to_unlazy_next() to __legitimize_mnt()
The tricky case (__legitimize_mnt() failing after having grabbed a reference) can be trivially dealt with by leaving nd->path.mnt non-NULL, for terminate_walk() to drop it. legitimize_mnt() becomes static after that. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
