[IPV6] NDISC: Fix is_router flag setting.
We did not send appropriate IsRouter flag if the forwarding setting is
positive even value. Let's give 1/0 value to ndisc_send_na().
Also, existing users of ndisc_send_na() give 0/1 to override,
we can omit redundant operation in that function.
Bug hinted by Nicolas Dichtel <nicolas.dichtel@6wind.com>.
