fixed the freeze on logout bug. The fix has several parts:
1) add a new parameter to queue_netbios_packet(), the "reply_id", this
is the id that should be used when sending a further response to the
packet (such as a response after we get back a reply to a name query
after senidnga WACK). reply_id is 0 (meaning unused) in most cases.
2) fix the id used in the reply in add_name_respond() from
response_name_query_register()
3) remember to remove the response record at the end of
response_name_query_register()
4) get the right IP address (it was 0.0.0.0) in
response_name_query_register()
5) add a new field reply_id to struct response_record
