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
