    s390: ism: Pass string literal as format argument of dev_set_name()

    GCC 14.2.0 reports that passing a non-string literal as the
    format argument of dev_set_name() is potentially insecure.

    drivers/s390/net/ism_drv.c: In function 'ism_probe':
    drivers/s390/net/ism_drv.c:615:2: warning: format not a string literal and no format arguments [-Wformat-security]
      615 |  dev_set_name(&ism->dev, dev_name(&pdev->dev));
          |  ^~~~~~~~~~~~

    It seems to me that as pdev is a PCIE device then the dev_name
    call above should always return the device's BDF, e.g. 00:12.0.
    That this should not contain format escape sequences. And thus
    the current usage is safe.

    But, it seems better to be safe than sorry. And, as a bonus, compiler
    output becomes less verbose by addressing this issue.

    Compile tested only.
    No functional change intended.
