[PATCH 3/7] hfs: remove ->writepage

[Christoph Hellwig <hch@lst.de>]

->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 stop
wiring up ->writepage for hfs_aops.
