doc: improve the description of __folio_mark_dirty

Patch series "Improve buffer head documentation", v3.

Turn buffer head documentation into its own document, and make many
general improvements to the docs.  Obviously there is much more that could
be done.  Tested with make htmldocs.


This patch (of 8):

I've learned why it's safe to call __folio_mark_dirty() from
mark_buffer_dirty() without holding the folio lock, so update the
description to explain why.
