[spp] [PATCH] shared: refactor func spp_check_core_update

[yasufum.o@gmail.com]

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

spp_check_core_update() is used for inspecting lcore information of
given ID is updated or not. If it is not updated, it returns SPP_RET_NG.
However, it is not appropriate NG for the case just made no changed.

This update is to change to return 0 if info is not changed, or 1. Name
of function is also changed to sppwk_is_lcore_updated() to be more
specific for the usage.
