Tested on Latitude E6440 and now userspace does not receive
KEY_KBDILLUMTOGGLE event, so does not try to change keyboard
backlight (which is already done by BIOS when key is pressed).

I suggest to backport this patch to stable kernels because this
problem is in all kernel versions which have dell-wmi.c driver.
