[spp] [PATCH] spp_vf: change exit command to return response

[x-fn-spp@sl.ntt-tx.co.jp]

From: Hideyuki Yamashita <yamashita.hideyuki@po.ntt-tx.co.jp>

For secondary processes use common process_request(), it causes an
error because spp-ctl expects a response but these processes do not
return anything. This patch is to change it to return message.
