Description of problem:
If I pass namei a path "a/b", where "a" exists but is not a directory, namei
ignores the "a" component and tries to access "b" in the current directory.  It
should complain that "a" is "Not a directory".

Version-Release number of selected component (if applicable):
util-linux-2.13-0.44

How reproducible:
Always

Steps to Reproduce:
$ mkdir foo
$ cd foo
$ touch a b
$ namei a/b
  
Actual output:
f: a/b
 - a
 - b

Expected output:
f: a/b
 ? a - Not a directory (20)
