libata: switch pio task from workqueue to slow-work A workqueue isn't a good fit for the pio task: - It does not require per-CPU support, thus wasting many threads. - The pio task would like to have more than one thread per CPU in some cases, for the single CPU case of having more than one pio device active. So convert to slow-work instead, this is now possible with support for delayed slow work and cancellation. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
