[spp] [PATCH 1/3] spp_vf: add sleep after disconnect detection

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

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

This update is for adding sleep() to add interval to reconnect.

Interval of accepting command is reduced to fix slow response
in previous patches, but still need to add another interval to
reconnect to spp-ctl.
