netfilter: don't set F_IFACE on ipv6 fib lookups
commit
47b7e7f82802dced3ac73658bf4b77584a63063f upstream.
"fib" starts to behave strangely when an ipv6 default route is
added - the FIB lookup returns a route using 'oif' in this case.
This behaviour was inherited from ip6tables rpfilter so change
this as well.
