Maybe it should be KERNEL && INVARIANTS, for the sake of userland apps
using queue.h which may have their own INVARIANTS define but not their
own panic(9) implementation?

> Add sanity checking for QUEUE(3) lists under INVARIANTS. Races may lead
> to list corruption, which can be difficult to unravel in a post-mortem
> analysis. These checks verify that prev and next pointers are consistent
> when inserting or removing elements, thus catching any corruption earlier.
> Also use TRASHIT to break LIST and SLIST link pointers on element removal,
> from mlaier via -hackers.
