ceph: convert page cleanup loop in writepages_finish() to folios

Browse source

Convert the page cleanup loop in writepages_finish() to work on folios.
Resolve the folio up front and unwrap any fscrypt bounce folio to its
page cache folio, storing the page cache page back into the array.

This removes a use of detach_page_private() and five calls to
compound_head() per page, while adding one back via page_folio().

While at it, remove the BUG_ON() in the num_pages loop, as it cannot be
triggered.

No functional change.
