When we snl_init_writer() we allocate memory in the struct snl_state in the struct pfctl_handle.
This memory was never released again, leading to a memory leak. We still
had a reference to the memory and would release it on pfctl_close()
(so valgrind did not detect it as a leak), but long-lived users (e.g.
bsnmpd) would eventually run out of memory.
Explicitly reset the snl_state when we're done to prevent this.
