keyboard.c: Stop flooding dmesg with useless warnings

[Parag Warudkar <parag.warudkar@gmail.com>]

I use  Apple keyboard and mouse which seem to generate events with 
keycode==0.

keyboard.c floods dmesg endlessly with below messages. This happens at a 
very fast rate and never stops, leaving the dmesg unusable.

[46591.960000] keyboard.c: can't emulate rawmode for keycode 0
[46591.996000] keyboard.c: can't emulate rawmode for keycode 0
[46592.032000] keyboard.c: can't emulate rawmode for keycode 0
[46592.068000] keyboard.c: can't emulate rawmode for keycode 0
[46592.104000] keyboard.c: can't emulate rawmode for keycode 0
[46592.140000] keyboard.c: can't emulate rawmode for keycode 0
[46592.176000] keyboard.c: can't emulate rawmode for keycode 0
[46592.212000] keyboard.c: can't emulate rawmode for keycode 0
[46592.248000] keyboard.c: can't emulate rawmode for keycode 0

The patch below avoids printing the warning if keycode == KEY_RESERVED.

If a more correct fix is possible please let me know and I will redo this.
(I suspect avoiding call to emulate_raw() with value ranges it cannot 
emulate might be a better fix?)

Otherwise please consider applying.
