[PATCH 02/13] driver core: Remove the link if there is no driver with AUTO flag

[Yong Wu]

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.

The ref_count of our device_link normally is over 1. When the consumer
device driver is removed, whole the device_link should be removed.
Thus, I add this patch.
