Subject: kern: make sure the queue macros are only used on queues

This turns mistakes as the one corrected in e59f05e9 into compile-time
errors.

* kern/queue.h: Add a new macro, queue_assert, and use it to assert
that all arguments given to the queue macros have the correct type.
* device/net_io.c (ENQUEUE_DEAD): Adapt to the fact that
`queue_next(q)' is no longer an lvalue.
