GRUB: don't spew "Unknown key 0xff" in error
Faulty keyboards make GRUB unusable. Normally it happens
when a user plugs in a faulty USB keyboard, but if it's
the laptop keyboard, then GRUB becomes unusable and the
user cannot boot anything.
So, your laptop keyboard is a ticking timebomb if you use
GRUB; with this patch, that's no longer the case.
