driver core: Fix error handling in driver API device_rename()
For class-device, device_rename() failure maybe cause unexpected link name
within its class folder as explained below:
/sys/class/.../old_name -> /sys/devices/.../old_name
device_rename(..., new_name) and failed
/sys/class/.../new_name -> /sys/devices/.../old_name
Fixed by undoing renaming link if renaming kobject failed.
Fixes: f349cf34731c ("driver core: Implement ns directory support for device classes.")
