ieee802154: Avoid calling WARN_ON() on -ENOMEM in cfg802154_switch_netns()
It's pointless to call WARN_ON() in case of an allocation failure in
dev_change_net_namespace() and device_rename(), since it only leads to
useless splats caused by deliberate fault injections, so avoid it.
Found by Linux Verification Center (linuxtesting.org) with Syzkaller.
