ipvs: zero usvc and udest
Make sure that any otherwise uninitialised fields of usvc are zero.
This has been obvserved to cause a problem whereby the port of
fwmark services may end up as a non-zero value which causes
scheduling of a destination server to fail for persisitent services.
As observed by Deon van der Merwe <dvdm@truteq.co.za>.
This fix suggested by Julian Anastasov <ja@ssi.bg>.
For good measure also zero udest.
