net-ipv6: fix excessive RTF_ADDRCONF flag on ::1/128 local route (and others)
There is a subtle change in behaviour introduced by:
commit c7a1ce397adacaf5d4bb2eab0a738b5f80dc3e43
'ipv6: Change addrconf_f6i_alloc to use ip6_route_info_create'
Before that patch /proc/net/ipv6_route includes:
00000000000000000000000000000001 80 00000000000000000000000000000000 00 00000000000000000000000000000000 00000000 00000003 00000000 80200001 lo
Afterwards /proc/net/ipv6_route includes:
00000000000000000000000000000001 80 00000000000000000000000000000000 00 00000000000000000000000000000000 00000000 00000002 00000000 80240001 lo
ie. the above commit causes the ::1/128 local (automatic) route to be flagged with RTF_ADDRCONF (0x040000).
AFAICT, this is incorrect since these routes are *not* coming from RA's.
As such, this patch restores the old behaviour.
