[PATCH] kqueue: Use 0 instead of NULL for udata

[Roy Marples <roy@xxxxxxxxxxxx>]

commit 2d826aee8c68edb6335befd44ef23ba4b7e7c5c1
Author: Roy Marples <roy@xxxxxxxxxxxx>
Date:   Wed Feb 10 20:32:10 2016 +0000

    Use 0 for udata instead of NULL for portability.
    NetBSD uses uintptr_t, others a pointer.
