[PATCH 7/9] dix: silence compiler warning

[Peter Hutterer]

inpututils.c:243:26: warning: comparison of constant 256 with expression of
type 'KeyCode' (aka 'unsigned char') is always false
[-Wtautological-constant-out-of-range-compare]
        if (modkeymap[i] >= MAP_LENGTH)
                    ~~~~~~~~~~~~ ^  ~~~~~~~~~~

MAP_LENGTH depends on MAX_BUTTONS which is somewhat arbitrarily chosen. We
don't expect this to ever change, but just in case leave the condition there
so the code is correct if we drop the number down.
