ipv6: add RTA_TABLE and RTA_PREFSRC to rtm_ipv6_policy


[ Upstream commit aa8f8778493c85fff480cdf8b349b1e1dcb5f243 ]

KMSAN reported use of uninit-value that I tracked to lack
of proper size check on RTA_TABLE attribute.

I also believe RTA_PREFSRC lacks a similar check.

Fixes: 86872cb57925 ("[IPv6] route: FIB6 configuration using struct fib6_config")
Fixes: c3968a857a6b ("ipv6: RTA_PREFSRC support for ipv6 route source address selection")
