ieee802154: Restore initial state on failed device_rename() in cfg802154_switch_netns()

Browse source

Currently, the return value of device_rename() is not acted upon.

To avoid an inconsistent state in case of failure, roll back the changes
made before the device_rename() call.

Found by Linux Verification Center (linuxtesting.org) with Syzkaller.
