ext2: convert iomap ops to ->iomap_next()

Convert ext2 iomap_ops to the new ->iomap_next() callback. The callback is
generated with the DEFINE_IOMAP_ITER_NEXT_END() 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.
