Fixed bug that John found in WINS server code. When nmbd as a WINS
server is sending out a name_query after a WACK, it needs to send
a packet with recursion_desired = 0 (yes Luke, you were right all
along :-). If it doesn't then if it's talking to itself then the
query packet ends up back in the WINS server instead of in the client
side code.
Makefile: Changed proto generation to stop including NMBDOBJ twice.
nmbd_namequery.c nmbd_packets.c nmbd_winsserver.c: Added extra
query_name_from_wins_server() code.
