[PATCH] aio: kill pointless ki_nbytes assignment in aio_setup_single_…

…vector io_submit_one assigns ki_left = ki_nbytes = iocb->aio_nbytes, then calls down to aio_setup_iocb, then to aio_setup_single_vector. In there, ki_nbytes is reassigned to the same value it got two call stack above it. There is no need to do so.
