Revert: "dell-laptop: Toggle the unsupported hardware killswitch"
This reverts commit a3d77411e8b2ad661958c1fbee65beb476ec6d70,
as it causes a mess in the wireless rfkill status on some models.
It is probably a bad idea to toggle the rfkill for all dell models
without the respect to the claim that it is hardware-controlled.
