ntfs: convert iomap ops to ->iomap_next()

Browse Source 
Convert ntfs iomap_ops to the new ->iomap_next() callback. Each callback is
generated with the DEFINE_IOMAP_ITER_NEXT()/DEFINE_IOMAP_ITER_NEXT_END()
macros, which wrap the iomap_iter_next() helper to finish the previous
mapping if needed and produce the next one. No functional changes are
intended.
