mm: fix VM_BUG_ON in __delete_from_swap_cache()
Patch series "Folio fixes for 6.0". This patch (of 2): The recent folio conversion changed the VM_BUG_ON() to dump the folio we're storing instead of the entry we retrieved. This was a mistake; the entry we retrieved is the more interesting page to dump.
