extfat: remove ->writepage

Patch series "start removing writepage instances v2".

The VM doesn't need or want ->writepage for writeback and is fine with
just having ->writepages as long as ->migrate_folio is implemented.

This series removes all ->writepage instances that use
block_write_full_page directly and also have a plain mpage_writepages
based ->writepages.


This patch (of 7):

->writepage is a very inefficient method to write back data, and only used
through write_cache_pages or a a fallback when no ->migrate_folio method
is present.

Set ->migrate_folio to the generic buffer_head based helper, and remove
the ->writepage implementation.
