Stefano Garzarella 9472083e64 scsi: fetch unit attention when creating the request 
Commit 1880ad4f4e ("virtio-scsi: Batched prepare for cmd reqs") split
calls to scsi_req_new() and scsi_req_enqueue() in the virtio-scsi device.
No ill effects were observed until commit 8cc5583abe ("virtio-scsi: Send
"REPORTED LUNS CHANGED" sense data upon disk hotplug events") added a
unit attention that was easy to trigger with device hotplug and
hot-unplug.

Because the two calls were separated, all requests in the batch were
prepared calling scsi_req_new() to report a sense.  The first one
submitted would report the right sense and reset it to NO_SENSE, while
the others reported CHECK_CONDITION with no sense data.  This caused
SCSI errors in Linux.

To solve this issue, let's fetch the unit attention as early as possible
when we prepare the request, so that only the first request in the batch
will use the unit attention SCSIReqOps and the others will not report
CHECK CONDITION.

Fixes: 1880ad4f4e ("virtio-scsi: Batched prepare for cmd reqs")
Fixes: 8cc5583abe ("virtio-scsi: Send "REPORTED LUNS CHANGED" sense data upon disk hotplug events")
