mac80211: make LED trigger names available early
The throughput trigger will require doing LED classdev/trigger handling before register_hw(), so drivers should have access to the trigger names before it. If trigger registration fails, this will still make the trigger name available, but that's not a big problem since the default trigger will the simply not be found.
