INPUT: keyboard_tasklet - don't touch LED's of already grabed device

[Aivils Stoss <aivils@unibanka.lv>]

Hi, Vojtech!

Recent kernels allow exclusive usage of input device when
input device is grabed. keyboard_tasklet does not check
device state and switch LED's of all keyboards. However
grabed device may be use another LED steering code.

This patch forbid keyboard_tasklet switch LED's of
grabed devices.
