ipv6: add link-local, sit and loopback address with INFINITY_LIFE_TIME
In the past the IFA_PERMANENT flag indicated, that the valid and preferred lifetime where ignored. Since change fad8da3e085ddf ("ipv6 addrconf: fix preferred lifetime state-changing behavior while valid_lft is infinity") we honour at least the preferred lifetime on those addresses. As such the valid lifetime gets recalculated and updated to 0. If loopback address is added manually this problem does not occur. Also if NetworkManager manages IPv6, those addresses will get added via inet6_rtm_newaddr and thus will have a correct lifetime, too.
