Adrian Hunter 2831eeb7bc driver core: Prevent warning when removing a device link from unregistered consumer 
commit e64daad660a0c9ace3acdc57099fffe5ed83f977 upstream.

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: 287905e68dd29 ("driver core: Expose device link details in sysfs")
