kernel-doc: allow structs whose members are all private

Struct members may be marked as private by using
	/* private: */
before them, as noted in Documentation/kernel-doc-nano-HOWTO.txt

Fix kernel-doc to handle structs whose members are all private;
otherwise invalid XML is generated:

xmlto: input does not validate (status 3)
linux-2.6.27-rc6-git4/Documentation/DocBook/debugobjects.xml:146: element variablelist: validity error : Element variablelist content does not follow the DTD, expecting ((title , titleabbrev?)? , varlistentry+), got ()
Document linux-2.6.27-rc6-git4/Documentation/DocBook/debugobjects.xml does not validate
make[1]: *** [Documentation/DocBook/debugobjects.html] Error 3
