buffer: convert block_page_mkwrite() to use a folio
If any page in a folio is dirtied, dirty the entire folio. Removes a
number of hidden calls to compound_head() and references to page->mapping
and page->index. Fixes a pre-existing bug where we could mark a folio as
dirty if the file is truncated to a multiple of the page size just as we
take the page fault. I don't believe this bug has any bad effect, it's
just inefficient.
