Bart Van Assche 94eb029370 fs/aio: Check IOCB_AIO_RW before the struct aio_kiocb conversion 
commit 961ebd1205 upstream.

The first kiocb_set_cancel_fn() argument may point at a struct kiocb
that is not embedded inside struct aio_kiocb. With the current code,
depending on the compiler, the req->ki_ctx read happens either before
the IOCB_AIO_RW test or after that test. Move the req->ki_ctx read such
that it is guaranteed that the IOCB_AIO_RW test happens first.
