[fireball] 40693: - Fix driver object type DeleteProcedure so that it actually unloads driver's image. - Make IopUnloadDriver work accordingly (it shouldn't try to unload an image when its object has already been deleted). Drivers can now be unloaded in ReactOS, this probably fixes a number of hardware-related applications and applications using hardware protection.
