[PATCH v2 3/5] nvme_fc: fix command id check

[jsmart2021 at gmail.com]

From: James Smart <jsmart2021 at gmail.com>

The code validates the command_id in the response to the original
sqe command. But prior code was using the rq->rqno as the sqe command
id. The core layer overwrites what the transport set there originally.

Use the actual sqe content.
