[PATCH loop_2013_01_04] fs: Fix a typo in aio_rw_vect_retry()

[Sedat Dilek]

Dave confirmed Jeff's suspicion in [1]:

> That wants to be rw_op = do_aio_write in the else clause.  How did you
> test this patch set?

Yep, that's certainly a bug. I concentrated on testing on loop mounts,
running some fio and ltp testcases, but I'm at a loss to explain how
things seem to work as well as they do. Let's see how where fixing this
leads.

This is a fixup to commit daf0f6142dd5 ("fs: use read_iter and write_iter
rather than aio_read and aio_write") from Dave Kleiklamp's GIT tree in [2].
