Subject: [PATCH] platform/x86: dell-wmi: Ignore new rfkill and fn-lock events

There are two new events generated by dell-wmi, rfkill and fn-lock, from
Dell Systems.

These events are for notification purpose, so we can ignore them.

Tested on XPS 9370.

I ordered them functionally instead of alphabetically, I can re-order
them to alphabetically if that's more diserable.
