Adrian Hunter e64daad660 driver core: Prevent warning when removing a device link from unregistered consumer
sysfs_remove_link() causes a warning if the parent directory does not
exist. That can happen if the device link consumer has not been registered.
So do not attempt sysfs_remove_link() in that case.

Fixes: 287905e68d ("driver core: Expose device link details in sysfs")
