simple fix to hopefully speed up srv_spoolss_replyopenprinter().

Use the client address from the pipe->conn->client_address
instead of trying to resolve the name in the _spoolss_rffpcn()
request.  Should make us more robust as well when the clients
are not registered in DNS or WINS.
(This used to be commit 23f0fcf6421b1e8dd6ed6ab14af14ea7eb380c1c)
