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.
