Mauro Carvalho Chehab f64c7e113d scripts: docs: kdoc_files.py: don't consider symlinks as directories
As reported by Randy, currently kdoc_files can go into endless
looks when symlinks are used:

	$ ln -s . Documentation/peci/foo
	$ ./scripts/kernel-doc Documentation/peci/
	...
	  File "/new_devel/docs/scripts/lib/kdoc/kdoc_files.py", line 52, in _parse_dir
	    if entry.is_dir():
	       ~~~~~~~~~~~~^^
	OSError: [Errno 40] Too many levels of symbolic links: 'Documentation/peci/foo/foo/foo/foo/foo/foo/foo/foo/foo/foo/foo/foo/foo/foo/foo/foo/foo/foo/foo/foo/foo/foo/foo/foo/foo/foo/foo/foo/foo/foo/foo/foo/foo/foo/foo/foo/foo/foo/foo/foo/foo'

Prevent that by not considering symlinks as directories.
