driver core: Remove the link if there is no driver with AUTO flag
DL_FLAG_AUTOREMOVE_CONSUMER/SUPPLIER means "Remove the link automatically on consumer/supplier driver unbind", that means we should remove whole the device_link when there is no this driver no matter what the ref_count of the link is.
