vhost-scsi: Fix vhost_scsi_send_status()

Although the support of VIRTIO_F_ANY_LAYOUT + VIRTIO_F_VERSION_1 was
signaled by the commit 664ed90e ("vhost/scsi: Set
VIRTIO_F_ANY_LAYOUT + VIRTIO_F_VERSION_1 feature bits"),
vhost_scsi_send_bad_target() still assumes the response in a single
descriptor.

Similar issue in vhost_scsi_send_bad_target() has been fixed in previous
commit. In addition, similar issue for vhost_scsi_complete_cmd_work() has
been fixed by the commit 6dd88fd5 ("vhost-scsi: unbreak any layout for
response").

Fixes: 3ca51662 ("vhost-scsi: Add better resource allocation failure handling")
