Properly initialize the message lists.
The message lists are implemented using a TAILQ from queue(3). The heads
of the list must be initialized using the provided macros, since the field
called 'tqh_last' is non-zero in the initial state. This patch fixes a
potential null pointer dereference by properly initializing the queues.
Note that there is no actual bug in the current code, because it uses the
lists in such a way as to initialize 'tqh_last' before any dereference.
