virtio-scsi: Cleanup of I/Os that never started
There is still a small window that occurs when a cancel I/O affects
an asynchronous I/O operation that hasn't started. In other words,
when the residual data length equals the expected data length.
Today, the routine virtio_scsi_command_complete fails because the
VirtIOSCSIReq pointer (from the hba_private field in SCSIRequest)
was cleared earlier when virtio_scsi_complete_req was called by
the virtio_scsi_request_cancelled routine. As a result, the
virtio_scsi_command_complete routine needs to simply return when
it is processing a SCSIRequest block that was marked canceled.
