using rawcb_mtx. Hold this mutex while modifying or iterating over the control list; this means that the mutex is held over calls into socket delivery code, which no longer causes a lock order reversal as the routing socket code uses a netisr to avoid recursing socket -> routing -> socket. Note: Locking of IPsec consumers of rawcb_list is not included in this commit.
