Add NI_NAMEREQD flag to getnameinfo() call. Without this flag,
getnameinfo() don't return error at name resolving failure.
But it is used at doaddrlookup(-N) case in telnet, error need to be
returned to correctly initialize hostname buffer.
Discovered at checking recent KAME repository change, noticed by itojun.
