exfat: convert iomap ops to ->iomap_next()

Convert exfat iomap_ops to the new ->iomap_next() callback. Each
callback is generated with the DEFINE_IOMAP_ITER_NEXT() and
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.
