driver core: Remove the link if there is no driver with AUTO flag
commit 0fe6f7874d467456da6f6a221dd92499a3ab1780 upstream.
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.
