scsi-disk: bump SCSIRequest reference count until aio completion runs
In some cases a request may be canceled before the completion callback
runs. Keep a reference to the request between starting an AIO operation
and the corresponding scsi_req_cancel or scsi_*_complete.
When a request has to be retried, the request can be dropped because
scsi_dma_restart_bh only looks at requests that are enqueued. As such,
they always have at least a reference.
