[PATCH] virtio-scsi spec: add per-LUN parameter query

Each virtio scsi HBA has global request queue limits. But the passthrough LUNs (scsi-generic) come from different host HBAs may have different request queue limits. If the guest sends commands that exceed the host limits, the commands will be rejected by host HAB. To address this issue, this patc
