bgpd: mp_unreach_nlri fs sent with no nexthop

FS UNREACH message with 0 NLRI inside is sent after each peer
establishment. FS can send NLRI messages with no nexthop.
The commit fixes a message that is triggered by mistake
if FS was about to be sent, then that message is not output.
Also it fixes a typo.
