[SCSI] gdth: fix Error: Driver 'gdth' is already registered, aborting...
This message appears on modprobe/rmmod/modprobe of the driver. It's
caused because if the driver has no instances, it returns an error
from gdth_init, which causes the module to fail to load.
Unfortunately, the module's pci driver is still registered at this
point.
Fix this by making gdth behave like a modern driver and insert even if
it doesn't find any instances (in case of hot plug or software driven
binding).
