[PATCH v5 12/22] zonefs: convert iomap ops to ->iomap_next()

Convert zonefs iomap_ops to the new ->iomap_next() callback. Each
callback is generated with the DEFINE_IOMAP_ITER_NEXT() macro, which
wraps the iomap_iter_next() helper to finish the previous mapping if
needed and produce the next one. No functional changes are intended.
