[PATCH] [Natty SRU] Revert: "dell-laptop: Toggle the unsupported hardware killswitch"

[Keng-Yu Lin]

SRU Justification:

Impact: turning off wi-fi using the hotkey permenantly disables
wireless networking. The only way to turn it on is reboot.

Fix: Revert the previous patch to toggle the killswitch via the
Dell-specified SMI command without the concern if it is hardware-controlled.

I sent the revert patch to upstream already, but it is not yet merged.
I issued the SRU for Natty in case of the concern of blocking the certification.

Testcase: Confirmed to fix the issue on Dell Vostro 1014 and Latitude 2120
