    drivers/ide-cd: Handle missing driver data during status check gracefully
    
    The 0day bot reports the below failure which happens occasionally, with
    their randconfig testing (once every ~100 boots).  The Code points at
    the private pointer ->driver_data being NULL, which hints at a race of
    sorts where the private driver_data descriptor has disappeared by the
    time we get to run the workqueue.
    
    So let's check that pointer before we continue with issuing the command
    to the drive.
    
    This fix is of the brown paper bag nature but considering that IDE is
    long deprecated, let's do that so that random testing which happens to
    enable CONFIG_IDE during randconfig builds, doesn't fail because of
    this.
    
    Besides, failing the TEST_UNIT_READY command because the drive private
    data is gone is something which we could simply do anyway, to denote
    that there was a problem communicating with the device.
