[PATCH] doc-guide: kernel-doc: add comment about formatting verification

[Mike Rapoport]

Currently there is no automated checking for kernel-doc comments except
running 'kernel-doc -v -none <filename>'. Mention the possibility to run
kernel-doc to verify formatting of the comments in the kernel-doc guide.
