[PATCH for-4.14] kdd: fix build again

[Wei Liu <wl@xxxxxxx>]

Restore Tim's patch. The one that was committed was recreated by me
because git didn't accept my saved copy. I made some mistakes while
recreating that patch and here we are.

Fixes: 3471cafbdda3 ("kdd: stop using [0] arrays to access packet contents")
