scsi: smartpqi: Fix driver synchronization issues
- Synchronize OFA and controller offline events. Prevent I/O during the
above conditions.
- Cleanup pqi_device_wait_for_pending_io() by checking the
device->scsi_cmds_outstanding instead of walking the device's list of
commands.
- Stop failing all I/O for all devices. This was causing OS to retry them,
delaying OFA.
- Clean up cache flush. The controller is checked for offline status in
lower level functions.
