Input: add safety guards to input_set_keycode()
commit cb222aed03d798fc074be55e59d9a112338ee784 upstream.
If we happen to have a garbage in input device's keycode table with values
too big we'll end up doing clear_bit() with offset way outside of our
bitmaps, damaging other objects within an input device or even outside of
it. Let's add sanity checks to the returned old keycodes.
