I realise that it is an error, what I want to know is, what is the
"approved" error response that the target should produce if this
situation occurs?

IMHO, a robust iSCSI implementation must be able to respond
appropriately to an out of order command that has been sent to it by
an initiator.

It's no good saying that it should never occur because the
specification disallows it. Remember, if it is possible for something
bad to happen then it WILL happen.
