iomap: remove unused private field from ioendiomap-5.13-merge-3

The only remaining user of ->io_private is the generic ioend merging
infrastructure. The only user of that is XFS, which no longer sets
->io_private or passes an associated merge callback. Remove the
unused parameter and the ->io_private field.
