input: fix up usage of button->down, used to be a bitmask, is now an array.

Browse Source 
device->button->down used to be a 32-byte bitmask with one bit for each
button. This has changed into a 256-byte array, with one byte assigned for
each button. Some of the callers were still using this array as a bitmask
however, this is fixed with this patch.

Thanks to Keith Packard for pointing this out. See also:
