[spp] [PATCH 1/5] spp_nfv: chage to return msg of exit command

[ogawa.yasufumi at lab.ntt.co.jp]

From: Yasufumi Ogawa <ogawa.yasufumi at lab.ntt.co.jp>

This patch is to fix error of receiving data of NfvProc in spp-ctl.
Spp_nfv returns no message after exit command while spp-ctl expects
to get any of message as a result. To fix, change to return empty
message.
