Shuhei Matsumoto 7bfbc388d7 nvmf/tcp: Pass extended LBA based length as I/O length to NVMf controller
When DIF is inserted or stripped,
- in the TCP transport layer, we can use LBA based length throughout, but
- in the NVMf controller layer and BDEV layer, extended LBA based
  length must be used, and NVMf controller gets the length from
  tcp_req->req.length.

Hence by adding and using two variables, elba_length and orig_length
to struct spdk_nvmf_tcp_req, set the extended LBA length to
tcp_req->req.length before calling spdk_nvmf_request_exec(), and then
restore the original LBA based length to tcp_req->req.length after
calling spdk_nvmf_tcp_req_complete().
