[spp] [PATCH] spp_nfv: fix buffer overflow

[yasufum.o]

From: Yasufumi Ogawa <yasufum.o@gmail.com>

String `port_set` is used for containing a set of src and dst ports for
returned message. It is formatted as 39 chars as following, although its
buffer size is 32.
  "{\"src\":\"%s:%d\",\"dst\":\"%s:%d\"}"  // 39 chars

This update is to fix the bug by increasing buffer size to 128 which is
enough for the usage.
