drivers/dma/ioat: Remove now-redundant smp_read_barrier_depends()
Now that READ_ONCE() implies smp_read_barrier_depends(), the __cleanup() and ioat_abort_descs() functions no longer need their smp_read_barrier_depends() calls, which this commit removes. It is actually not entirely clear why this driver ever included smp_read_barrier_depends() given that it appears to be x86-only and given that smp_read_barrier_depends() has no effect whatsoever except on DEC Alpha.
