inet: fix inet_fill_ifaddr() flags truncation
I missed that (struct ifaddrmsg)->ifa_flags was only 8bits,
while (struct in_ifaddr)->ifa_flags is 32bits.
Use a temporary 32bit variable as I did in set_ifa_lifetime()
and check_lifetime().
Fixes: 3ddc2231c810 ("inet: annotate data-races around ifa->ifa_flags")
