netfilter/ipvs: clear ipvs_property flag when SKB net namespace changed
When run ipvs in two different network namespace at the same host, and one
ipvs transport network traffic to the other network namespace ipvs.
'ipvs_property' flag will make the second ipvs take no effect. So we should
clear 'ipvs_property' when SKB network namespace changed.
Fixes: 621e84d6f373 ("dev: introduce skb_scrub_packet()")
