Currently the NVMe target stores the expexted data length in req->data_len and uses that for data transfer decisions, but that does not take the actual transfer length in the SGLs into account. So this adds a new transfer_len field, into which the transport drivers store the actual transfer length. We then check the two match before actually executing the command. The FC transport driver already had such a field, which is removed in favour of the common one.
