nfs/localio: remove 61 byte hole from needless ____cacheline_aligned 



struct nfs_local_kiocb used ____cacheline_aligned on its iters[] array
and as the structure evolved it caused a 61 byte hole to form.  Fix
this by removing ____cacheline_aligned and reordering iters[] before
iter_is_dio_aligned[].
