mm: fix VM_BUG_ON in __delete_from_swap_cache()

Browse source 
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.
