s3:winbindd: don't ignore 'result' in wb_dsgetdcname_done()
Ignoring it could cause a segfault in winbindd_getdcname_recv()

commit 40ae8b74b669ced9dee0c33e15bc5e0ac8680506

s3: Remove smbd_server_fd() from write_data()
This completely removes the DEBUG(0, ..) error message from write_data(). I've
gone through all callers of write_data() and made sure that they have their own
equivalent error message printing.
