scsi: smartpqi: Take drives offline when controller is offline
During a controller lockup, the physical and logical drives under the
locked up controller are still listed at the OS level. I.e. the
controller is offline but the status of each drive is 'running'.
When the controller is unexpectedly taken offline, show its drives as
offline.
