Force input device changed callback when Keyboard layout info is updated

Virtual keyboard creation uses KEYBOARD_LAYOUT_ASSOCIATION reconfig to
associated input device with keyboard layout info. But this can
happen after input device added (Race condition between device creation
and input device added callback.)
If input device already added then we sometimes don't get input device
changed callback since the generation is same.
