ipv6: Fix use of anycast address with loopback
Thomas reported a regression with IPv6 and anycast using the following
reproducer:
echo 1 > /proc/sys/net/ipv6/conf/all/forwarding
ip -6 a add fc12::1/16 dev lo
sleep 2
echo "pinging lo"
ping6 -c 2 fc12::
The conversion of addrconf_f6i_alloc to use ip6_route_info_create missed
the use of fib6_is_reject which checks addresses added to the loopback
interface and sets the REJECT flag as needed. Update fib6_is_reject for
loopback checks to handle RTF_ANYCAST addresses.
Fixes: c7a1ce397ada ("ipv6: Change addrconf_f6i_alloc to use ip6_route_info_create")
