    NVMe-oF: Fix generation of hostnqn file

    In some old nvme-cli versions the NVMe-oF create_hostnqn method fails.

    This happens specifically on versions between not having the
    show-hostnqn command and having it always return a value. On those
    version the command only returns the value present in the file and never
    tries to return an idempotent or random value.

    This patch adds for that specific case, which is identified by the
    stderr message:

       hostnqn is not available -- use nvme gen-hostnqn
