[IPVS]: Update mark->cw in the WRR scheduler while service is updated.

ChangeSet 1.1448.127.3, 2005/03/09 20:37:15-08:00, [email protected]

	[IPVS]: Update mark->cw in the WRR scheduler while service is updated.
	
	It's for better performance in the WRR scheduling when server weight is adjusted.
	The change is ported from the changes of IPVS in kernel 2.6. Thanks must go to
	Kees Hoekzema <[email protected]> for finding the WRR problem in kernel 2.6.
