[Natty SRU/Oneiric FYI] Fix Realtek RTL8192ce LED in Ubuntu

[Stefan Bader]

SRU Justification:

Impact: The driver code for the RTL8192ce wireless driver does not
initialize the LED which does not allow to quickly check whether
wireless is enabled.

Fix: Upstream commit from v3.0-rc1. The matter is not seen as critical
upstream, so there will not be stable update.

Testcase: Patch verified by reporter to enable LED.

Note: as this is in v3.0-rc1 it is currently not in Oneiric, but likely
will be by the time of release. Sending the Oneiric patch as informational
piece. To work in Natty one variable had to be renamed.
