ipv6: Set cfg.ifa_flags before device lookup in inet6_rtm_newaddr().
We will convert inet6_rtm_newaddr() to per-netns RTNL.
Except for IFA_F_OPTIMISTIC, cfg.ifa_flags can be set before
__dev_get_by_index().
Let's move ifa_flags setup before __dev_get_by_index() so that
we can set ifa_flags without RTNL.
Also, now it's moved before tb[IFA_CACHEINFO] in preparing for
the next patch.
