Martin K. Petersen 919f797a4c SCSI: Fix error handling when no ULD is attached 
Commit 18a4d0a22e ("[SCSI] Handle disk devices which can not process
medium access commands") introduced a bug in which we would attempt to
dereference the scsi driver even when the device had no ULD attached.

Ensure that a driver is registered and make the driver accessor function
more resilient to errors during device discovery.
